Is Tesla potentially putting the public at risk with it’s cost-cutting strategy?

I’ve made no attempt to hide the fact that I’m not a fan of Tesla. It was never about the technology, but rather their business practices and the way they treat their customers. However, that may be about to change with what I would consider to be a penny wise, but pound foolish decision to remove radar and ultrasonic sensors from it’s vehicles.

In a report from Electrek, Tesla is basically saying that they’re going all-in on computer vision and dropping other sensors with the laughable justification that it’s how humans navigate. Considering the potential consequences, perhaps laughable isn’t the right word.

One of the features that impressed me the most about Tesla’s early self-driving feature was the integration of radar data. A perfect example of this can be found in this 2016 video of a Tesla detecting a vehicle several cars ahead that was moving slowly/braking and was able to avoid an accident. You can’t see the vehicle ahead as it’s completely obscured, but the Tesla radar could. Can a Tesla camera system do the same? Maybe, but I’m not sure I’d want to trust an autopilot system without radar. (or some other form of beyond visual spectrum object detection)

Tesla’s track record with self-driving cars hasn’t exactly been fool-proof either. (even with the additional sensors) I’ve been in Teslas that have had difficulty in daylight with the painted lines of the road. There have also been numerous incidents reported where autopilot didn’t see a crossing/oncoming vehicle resulting in fatalities. Beta testing software features is fine for the consumer smartphone and computer industries, but it shouldn’t be something that happens in cars on public roads with safety-critical systems.

Tesla does state in their announcement that “at this time, [they] do not plan to remove the functionality of ultrasonic sensors in [their] existing fleet.” Hopefully the same is true for the radar sensors as well. This appears to be targeted at new production models only with models 3 and Y, and later the S and X.

This Reuters article from early June explains some of the details of why a camera-only system could be less safe than one with additional radar sensors. Tesla may think they’re saving (making) money removing the sensors and making development easier for themselves, but not tackling the more difficult problem of integrating different sensors leaves gaps that may put people’s lives at risk.

Update 12/2022: Drivers of new vision only Tesla models already running into problems, some features not yet available

Update 12/16/2022: Tesla appears to be reversing course and bringing radar back based on FCC filing. Elektrek quoted the same tesla filing indicating Tesla would be marketing a new HD radar in mid-January of 2023. This is good news for potential new buyers and potentially for improvements in FSD, but what about those who bought the stripped down versions? If I were one of those customers, I wouldn’t be too happy.

Car Updates 2022

The past year has been an interesting ride for sure. While I didn’t get to race at all, I did manage to attend a few track days at the beginning of the year, even though the MINI needed a new clutch. In my last (car-related) post I bid farewell to our old E39, but I didn’t mention what had replaced it.

Originally I was trying to find another 5-series as I had really enjoyed the comfort of the E39. (it’s still the most comfortable car I’ve ever driven) I looked around at used F10 and F90 550 and M5 models, but was warned about the engines by my mechanic.

I sat down and thought about what it was that I really wanted and it came down to a few things: sporty, manual transmission, (no flappy paddles) decent horsepower and comfortable.

I looked at a lot of cars online for a little over a year, but eventually I started to settle on either BMW or Porsche. On the Porsche side, I’ve always loved the Cayman. Having never driven a mid-engine sports car this was definitely an interesting choice. However after scouring the internet for months, I realized that Porsches hold their value far too well. I would need to settle for a significantly older model to afford one and it would also be significantly less practical as a 2-seater.

Swinging back to the BMW side, I decided that if I was going this way, I wanted a M car. One day I stumbled on a listing for a 2016 M4 in Yas Marina blue with decent miles and seemingly in great condition. As a number of cars had already slipped through my fingers, I didn’t get my hopes up, but to my surprise the car was still available the following Saturday. I set an appointment with the dealer that was about a 3hr drive away, cleaned out the E39 and drove up with the family.

Everything went well, the car checked out (I even brought my BMW scan tools to verify) and I ended up trading the E39 for it that day.

My F82 M4

Over the last year, I’ve really enjoyed having this as my daily driver. It’s admittedly a lot of car for that role and I’m sure some would wonder why I’d choose it. However, I’ve always thought that cars were meant to be driven, not to be collectors items. This M4 is about as close to my goal as I could achieve. It’s probably the last generation of fully manual gasoline-powered M model that BMW will produce and far more attractive than the current model. I want to enjoy this last era of full manual, dinosaur-burning muscle before they’re all gone and we’re relegated to driving (or being driven by) a computer on wheels.

Farewell Project E39!

Our first trip with our E39 530i M-Sport in the Blue Ridge mountains of NC

After 10 years and many adventures, it was finally time to let our E39 start the next part of its journey. While we certainly had our fair share of issues, I can honestly say I’m going to miss this one. The E39 530i M-Sport package with the 5-speed manual gearbox was a relatively rare and special bird. It was a true drivers car and one of the best examples of the end of the classic era of BMW design.

The E39 530i bridges 2 eras of BMW design with a foot in the past, but another firmly in the future. Our 530i was the modernized, or LCI version being a 2002 model. It had a more advanced software system, a more advanced version of the engine and electronics. In many ways it felt like a more modern car, while retaining a look that was decidedly retro, but one that had been smoothed rather than having the more harsh edges of models past.

This of course came with its own set of issues. The more advanced engine was all aluminum construction, had variable valve timing on both intake and exhaust and a load of additional sensors and more advanced ECU to control it all. Our car had a catastrophic cooling system issue prior to our ownership and this would have

consequences during our ownership. The good thing about owning a car with issues is that, if you’re so inclined, you can learn a lot along the way. I took full advantage of this and can honestly say that there isn’t a single system within this car that I didn’t work on in some way or another. From the engine, transmission, exhaust, to the electronics and interior, I learned it all.

This is both one of the best things and worst things about owning this car. While there were certainly frustrations to be had, I did learn a lot about how BMWs work (and modern cars in general) from this experience. Perhaps strangely, this experience also generated a type of attachment to this inanimate object that makes me miss it now that it’s gone. However, at over 200,000 miles and counting, and with more parts starting to show their age, it was definitely time to look for something that was less of a project and more of a dependable everyday vehicle.

Installing an Android-based navigation/multimedia system in the E39

Over the years, I’d fixed and modernized the E39 adding features like a modern touch-screen navigation system, a dashcam for recording my daily commute and upgraded stereo system so I could enjoy better sound along the way. Even so, the 530 was starting to show its age. The leather on the drivers seat had become worn to the point of panels starting to separate on the seat back. The passenger seat developed an issue with the boden-style drive cables that prevented it from being able to be adjusted. I did a temporary fix to get this working again, but it was a 4-hour nightmare due to how tightly packed the mechanicals are and how heavy and awkward the seat is to handle. There were also relatively recently replaced plastic/rubber parts that were already starting to fall apart, probably due to being new old-stock units that had aged in storage. In the end, it was down to choosing to continue to dump a decent amount of money into bringing the E39 back to its former glory, or invest in a new platform. In the end, I chose the latter and while I’m happy with that decision, I’m definitely going to miss the E39. Farewell my old friend!

All cleaned up and looking shiny (at least from 10ft away!)
