In 1929, before the Great Depression, the world had 32,028,500 automobiles in use, and the U.S. automobile industry produced over 90% of them. At that time, the U.S. had one car per 4.87 persons. After 1945, the U.S. produced about 75 percent of world's auto production. In 1980, the U.S. was overtaken by Japan and then became world leader again in 1994. In 2006, Japan narrowly passed the U.S. in production and held this rank until 2009, when China took the top spot with 13.8 million units. With 19.3 million units manufactured in 2012, China almost doubled the U.S. production of 10.3 million units, while Japan was in third place with 9.9 million units. From 1970 (140 models) over 1998 (260 models) to 2012 (684 models), the number of automobile models in the U.S. has grown exponentially.

Early car manufacturing involved manual assembly by a human worker. The process evolved from engineers working on a stationary car, to a conveyor belt system where the car passed through multiple stations of more specialised engineers. Starting in the 1960s, robotic equipment was introduced to the process, and today most cars are produced largely with automated machinary.

SAFETY

Safety is a state that implies being protected from any risk, danger, damage, or cause of injury. In the automotive industry, safety means that users, operators, or manufacturers do not face any risk or danger coming from the motor vehicle or its spare parts. Safety for the automobiles themselves implies that there is no risk of damage.

Safety in the automotive industry is particularly important and therefore highly regulated. Automobiles and other motor vehicles have to comply with a certain number of regulations, whether local or international, in order to be accepted on the market. The standard ISO 26262, is considered one of the best practice frameworks for achieving automotive functional safety.

In case of safety issues, danger, product defect or faulty procedure during the manufacturing of the motor vehicle, the maker can request to return either a batch or the entire production run. This procedure is called product recall. Product recalls happen in every industry and can be production-related or stem from raw material.

Product and operation tests and inspections at different stages of the value chain are made to avoid these product recalls by ensuring end-user security and safety and compliance with the automotive industry requirements. However, the automotive industry is still particularly concerned about product recalls, which cause considerable financial consequences.

Meanwhile, in self-driving car circles

*They don’t work.

https://blog.piekniewski.info/2019/11/18/late2019-the-wizards-of-oz/

Self driving cars

As time goes, more and more cracks are showing on the self driving car narrative. In June, one of the prominent startups in the competition - Drive.ai got acqui-hired by Apple, reportedly days before it would have ran out of cash. For those not well versed in startup valuation, this is not the best imaginable outcome. Startup employees are typically getting stock options (an option is basically a contract that allows one to buy a given number of shares at a fixed price), often trading off better salary they'd earn in an established company. These options are typically for common stock - in ways the least secured part of the equity structure. Investors buy shares of a company in investment rounds and often get at least in part what is called a preferred stock and other forms of liquidation preference.

 This means that in the event of liquidation, those shares will need to get payed off first, before any of the outstanding common shares. In any case the best outcome for a startup is an IPO (Initial Public Offering) when the shares get registered and can be traded freely at an open market, or an acquisition at a highest possible valuation. At high valuations the preferred stock effectively becomes same with common stock and common stock holders and option holders can cash out. However when the valuation at the acquisition is low, there may not be enough to cover the preferred stock (or any outstanding debt or convertible notes) in which case the common stock holders end up with nothing (and option holders can even end up negative if they exercised them). Anyway, long story short, this seems to be the case at drive.ai since they've been showing signs of financial distress earlier this year. As a curiosity, one of Drive.ai cofounders is Andrew Ng's wife, apparently having a spouse AI prodigy was of little help to the problem. Voyage, another similar startup now wants to solve the self driving problem with Deep Reinforcement Learning. Why? Because this is the latest buzzword in AI circles. Does it make any sense? None at all, since it can only work in simulation and as we all know in theory there is no difference between simulation and reality, but in reality there is. Anyway, autonomy is all about the corner cases and the nasty thing about corner cases is exactly that they were not anticipated by anybody, and consequently cannot be simulated.

Other self driving car players have been getting somewhat mixed press as well. Cruise is apparently plagued with glitches, one of Alphabet's execs admitted that there has been much hype in the space, while Waymo's valuation got pretty seriously (40% !!!) slashed by Morgan Stanley. Not surprisingly Waymo, which is typically rather quiet in media, rolled out a big PR offensive, started showing off cars without drivers (remote supervised) driving around Phoenix suburbs and inviting automotive journalists for a ride. I view this as an attempt to regain control over the crumbling narrative, which may be effective for a while.  For those who never visited Phoenix, the suburbs where Waymo tests their cars near Chandler AZ are pretty much the ideal case for an AV - wide streets, few pedestrians (especially in the summer when it is really hot). I visited that area this summer and saw a bunch of these Waymo cars myself, pointlessly cruising around like some lost sheep without a purpose.

We've also learned a few new facts about the infamous Uber incident, apparently Uber AVs were involved in some 37 crashes before the fatal accident in Arizona last year,  while “The system design did not include a consideration for jaywalking pedestrians,” as we learned from a stunning NTSB report. This may explain why Uber is now looking to pay for Waymo tech while their ex AV boss-star responsible for Uber-Waymo fiasco, Anthony Levandowski got charged with trade secret theft, facing many years in prison time.  I'm old enough to remember when Anthony's startup -Otto - was delivering beer in Colorado to great fanfares, something I've mentioned in this blog before, back in 2016.  

Meanwhile Daimler joined the crowd of companies slowly deflating the self driving balloon, to the point of even admitting they'd be cutting spending on it.

Tesla keeps the story up with promises of a million of self driving cars by 2020 - they raised money in May based on that promise so they need to keep it alive. While the stuff that Tesla does is in many ways impressive - recent talk by Andrej Karpathy - head of AI there -  revealed some of the details, the grim reality is that as of today even unusual illumination is able to throw the system off. To get the idea of how far way is Tesla from autonomy it's enough to search Youtube to see hundreds of failures, particularly with recently released enhanced summon. I keep my prediction that there will be exactly zero fully autonomous Tesla's in 2020, and most likely 2021, 2022 and at least 2023. I would not expect anything really usable by 2025 and that is only given that somebody finally makes a scientific breakthrough. If that fundamental shift does not happen, chances are self driving cars will remain a pipe dream for a few decades or more (aside maybe from some heavily geofenced, low speed local services, such as for example at a university campus).

In general the sentiment regarding autonomous vehicles seems to be changing with more prominent news outlets pouring buckets of cold water on the technological hot shots e.g. [1], [2], [3].

Finally since we are on technological hot shots, I had the pleasure to meet George Hotz, the founder of Comma.ai and a known hacker. Earlier this year Comma moved to San Diego, since in George's own words "San Francisco is a scam". He attended the same event at UCSD where he gave a somewhat entertaining and amusing talk in which he called self driving "a scam". Anyway, Comma is "proudly delivering level 2 autonomy", which is pretty much in line with the functionality of Tesla autopilot, only their system actually has driver monitoring which I think is a huge plus. Anyway, I would not let their hackish software ever talk to the CAN bus in my car and I certainly do not recommend anyone to do so - CAN allows to essentially control every aspect of the vehicle and any code responsible to controlling the vehicle should adhere to strict safety standards such as ISO 26262. On the other hand I have a suspicion Tesla does not adhere to these standards either...

The possibility of cyber security problems increases as cars become more networked. Embedded systems are vulnerable to hacking and unauthorized access, threatening drivers’ privacy and safety. Strong cyber security protections are necessary.

3. Limited upgradeability:

Although some embedded systems accept software upgrades, there may be hardware limitations that impede the addition of new technology. Hardware component updates can be complicated and costly, and they may cause obsolescence issues.

4. Rigid Design:

Specific functionality is commonly considered when creating embedded systems. Adapting to new requirements or technological breakthroughs may be challenging without significant changes to the hardware or software architecture.

5. The cost of development and maintenance:

It can be expensive to create and maintain embedded systems for VCU designs. Higher total vehicle expenses may result from both the initial development cost and the need for ongoing maintenance and updates.

6. Vendor Dependence:

When obtaining embedded system components, automakers may need to rely on specific manufacturers or providers. This reliance may limit adaptability and increase susceptibility to supply chain disruptions or changes in vendor affiliations.

7. Limited Processing Capacity:

As vehicle functionality advances, the processing capability of embedded systems may become a limiting factor. High computing needs may put a strain on embedded processors, especially when it comes to complex AI algorithms and autonomous driving.

8. Integration Challenges:

It might be challenging to combine embedded systems with other electronic components found in cars. Careful control of compatibility issues and communication protocols is required to ensure smooth operation and avoid system conflicts.

9. Environmental challenges:

Harsh external conditions, such as extreme temperatures and vibrations, can have an impact on the dependability of an embedded system. For automotive applications, it is critical to ensure that these systems are resistant to such circumstances.

10. Long development cycles:

Because of the stringent testing and certification procedures, embedded system development cycles for automotive applications can be lengthy. As a result, cutting-edge technology may not be applied as quickly as intended.

Conclusion:

Finally, embedded systems play a critical role in the design of vehicle control units (VCUs), considerably adding to the efficiency, safety, and overall performance of modern cars. Embedded systems are the technological backbone that allows the integration, processing, and control of various processes inside the VCU design.
