this is a reaction time problem with the current processing capability of the AP computer. I suspect this issue goes away (or becomes extremely rare) on HW3.
I don't think so.
Phantom braking is a plague for auto-pilot/auto-steer solutions across multiple OEM brands: Tesla, BMW, Honda, VW.
At least those are the ones I've experienced doing it first-hand, so far.
Some of that is camera mis-characterizing dark patches as cars (Mobileye and Tesla), or failing to correlate road turns with incoming traffic trajectory.
Some of that is radar doing the same as above.
Some of that are software bugs.
Phantom braking is a PITA, but you sort-of learn to anticipate conditions when it's likely to occur, and can over-ride it with your foot on the accelerator. Driving on one-lane roads with cars parked along the shoulder is guaranteed to trigger phantom braking even if there is plenty of room in the lane. Same for curved roads with incoming traffic. Same for shadows/overpasses.
There is one of the reasons why all quasi-autopilots, including Tesla's, keep remind drivers to stay alert, and be prepared to take over control of the car.
This is one of those reasons.
