There are multiple tells that this move, just like the removal of radar, is supply-chain and cost-driven and not actually driven by engineering. If this were a planned move, the software would already be ready to replace it. It is not. Cars without radar still aren't at parity with the car that have it, although they "fixed" this a few weeks back by simply turning off the radar on the older cars. The parking sensors…

When you have a several month wait list for your product, legions of devoted potential customers, if you're head and shoulders above any of your competitors, you're able to get away with things like this.

Especially if your customers don’t give a shit about the safety of others.

“In the near future, once these features achieve performance parity to today’s vehicles” Right... like how vision vehicles have parity with autopilot speeds and following distance? Oh wait they don't. Vision-only vehicles are still limited to a max of 85mph and 2 car minimum following distance for autosteer while radar is 90mph and 1 car following distance. Texas has 85mph highways. The two car following distance con…

What's the point of using car lengths as a metric of follow distance.

I'd love to see the convincing data RE: radar - they're using the same radars as every other car that has emergency braking from the car in front of the car that's in front of you. I've not heard of many "phantom braking" sessions from these other vehicles - I may have missed something.

Karpathy covered it during a conference keynote here: https://youtu.be/g6bOwQdCJrc?t=1368 It also is pretty common with other vehicles, they just don't get as much press as Tesla: https://www.rivianownersforum.com/threads/phantom-braking-an... https://www.fox43.com/article/news/feds-try-to-determine-why...

However phantom breaking still happens regularly (and perhaps more often) with their vision system. Shadows really mess with it.

So I’m not sure that’s very compelling that radar is somehow making things worse for them.

I have had a model 3 for four years and the autopilot has steadily gotten worse. In summer 2019 we went on a road trip that was 10 hours of total driving (each way), where I actually drove for maybe 30 mins total. It was flawless and downright magical. Since then we often have the car slam brakes out of the blue (once waking up my sleeping family and causing both kids to cry), and a few other times. I have lost trust…

I drove a new M3 in Germany last week and was blown away by how well the assisted driving features worked. Below 60 kmh it also allows you to never touch the steering wheel while on the highway in a traffic jam.

For my purposes it seemed superior to the current Tesla system and after watching some comparison videos, my conclusion seemed accurate.

> The parking sensors on the Tesla are really good and very useful. I respectfully disagree. I think their primary use case is parking. Tesla does a really good job with automatic parking, and it IS useful especially for parallel parking. But honestly, I have curbed my rims and hung up my underbody front spoiler on a curb and they did not help. Really there is an opportunity for cameras to protect the car from nearby…

Tesla is probably the WORST at automatic parking. Here’s a comparison against some other competitors.

My own model Y has maybe successfully automatically parked 2/10 times. Most of my friends and coworkers have similarly low success rates.

In your sentence are you referring to a BMW M3? Since Tesla also have an M3 (edit: albeit abbreviated) I was a tad confused by your second paragraph

Tesla is technically Model 3, not M3

I get phantom forward collision warnings on my car quite often, a 2015 VW Jetta TDI SEL. There are a few places where it triggers ~1/3 of the time while driving on a clean road with no other cars around in either direction.

The system doesn't trigger breaking just a warning alarm beep and dash screen warning message, but all these systems are unreliable at this point, even the newer ones have these same false positives and false negatives.

It is but a lot of folks shorten it to M3 as well.

They are wrong. A truly unbelievable coincidence coming across this article, I just got rear-ended by a Model 3 this morning. Low speed, I'd figure about 10 mph tops: A softball to end all softballs for AEB, and somehow I got hit with considerable force. We've had radar based systems that would have avoided this since the 2000s. I work in the self-driving space and while it's not an apples to apples comparison becaus…

Was the Tesla being driven in the FSD mode? or was this a simple human error?

I feel that may be irrelevant - my 2019 honda odyssey will stop me no matter what. All lane departure / following, cruise control, etc can be off - but automatic emergency braking / anti colission will work. I would not have it otherwise - I do not have any automated stuff in my old wrx, but I wanted all the safety always in the car with my family.

(it is crazy to me how many brands only have the good safety stuff as part of some ridiculous 9000$ sunroom and leather and Sirius xm package / trim ;-< )
