I got a Volkswagen with front assist and adaptive cruise control. I use it mainly for long runs with little traffic, that way my foot doesn’t get cramped for staying at the same position.

When crossing under some bridges, sometimes it decelerates and warns me of a collision, even if there is no one there. I have to override it by stepping on the gas pedal until I’m through.

I’ve also felt it hiccup on a test strip where they were testing radars, I was guessing it was due to them using similar frequencies, but I’m not sure on that one.

Exactly why Tesla switched to vision only

Nah, that was cost.

Why include a (much more expensive) FSD computer in every Tesla then, if it was just a cost-saving measure and radar is actually needed for self-driving? FSD works better today with vision only than any other solution with vison+radar.

The computer was needed anyway to get sensor fusion and reasoning about environment around, so it's not something that was "added" or "more expensive".

Also, their original solution did sensor fusion with LIDAR, but the vendor find out and blew a gasket - because the LIDAR sensors weren't designed for safety-critical operation and to my understanding became a potential liability for the maker if they continued to supply them for incorrect use knowingly.

When did Tesla have LIDAR?

My bad, it was RADAR, not LIDAR, with Musk explicitly saying how it was better because unlike optical systems it wasn't blocked by bad weather so much.

I unfortunately don't have link about supplier dropping them - I do recall it was a bit of a scandal at the time but it quickly got overshadowed with other issues and well, FSD not working right was "business as usual"

Wrong. You’re thinking of tesla dropping mobileye back in like 2014. Nothing to do with ditching radar last year

Completely incorrect and made up.

IIRC from greentheonly’s twitter, there’s evidence of a brief experiment to do early fusion of vision and radar in the perception model
