For now, though, it looks like Tesla is building a case after they decided to do away with radar. I recall EM saying that it looks ugly and expensive too. I really got confused when Telsa came up with this patent though https://twitter.com/iamkellex/status/1534240730633236480?s=2...
No one sensor will work for all use cases; each has pros and cons. Radar really shines with depth sensing; it can cut through rain, fog, and snow like a hot knife through butter, much better than pure vision-based systems. At the same time, it seems to fail during harsh breaking and maybe a few other scenarios.
Leaning further into their vision systems when their vision systems cause their cars to slam into emergency vehicles that aren't even in travel lanes, and to rear-end tractor trailers, isn't encouraging. Musk is placing the rest of us at risk and I'm sick of it.
So I’m not sure that’s very compelling that radar is somehow making things worse for them.
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.
This isn’t the case with braking. You want to have a high degree of confidence in that scenario because you don’t want to cause an accident. It’s better to react later to an impending collision than it is to cause an accident that would have never happened.
It also is pretty common with other vehicles, they just don't get as much press as Tesla:
