But radar only does anything for detecting cars in front of you, so the only deficiency by removing it is using vision to perform that distance-keeping when using traffic-aware cruise control, which is not a pain point in my 2022 M3LR even in the rain.

But it used to be better: it was able to follow closer to the car in front--which is really important when you are in stop-and-go 3mph traffic on the highway--and it was supposedly able to see under the car in front of you (reflecting off the highway) to track the car ahead of them <- a friend of mine who's entire family is super into Tesla has all cars with the radar sensors, and when I was driving her around she was commenting about how many dumb decisions the newer Model 3 I have been renting was making, seemingly because of this. She was not happy about it when she heard Tesla started deactivating radar in old cars. But yeah: the feature minimally seems to work well enough--...even surprisingly well!--given the lack of having the sensors that Tesla previously swore were amazing, and so in some sense that particular cost cutting measure was a success. I was even thinking of buying one to own... but then they removed the parking sensors, and frankly that feature only barely works WITH the sensors--I drive a ton of random cars as I am always renting stuff, and the Tesla's parking radius feature is a cool UX but has tons of slop and has massively high latency... it is frankly just super dumb--and I cancelled my order when it finally arrived a week after it was for sure I wouldn't have the sensors. Regardless, though, even if you feel it works perfectly, radar was another situation of just hastily scrapping stuff and working on it in the field, as they removed the sensor before they had the software which was tolerable, and then they just kept promising people it was going to get better as they frantically tried to turn their marketing into reality. Over time it got better and after a long time it finally started to work at higher speeds, but for a long time it had a cap lower than the in-practice speed of even my nearby highways here in the United States, and still hasn't managed to regain all of the functionality of the prior design. Can you imagine Apple removing a sensor in a new iPhone without already having the software to replace it, and then just promising new customers they'll figure it out in the hope it doesn't affect sales?
