Is the Tesla 3 using stereo cameras _only_?

I thought most of these ADAS systems had some form of sensor fusion, combining multiple systems like: Stereo camera + front radar + long range US ... etc.

This is a scenario that would be safely avoided with an entry-level AEB system, is there something special about Tesla's design that I am missing?

I think they have a front radar. The trouble with those is differentiating stationary stuff like bridges from stationary stuff like overturned trucks.

I think negating low-hanging bridges is one of the scenarios OEMs specifically calibrate for with auto manufacturers. It's not rocket science it's a tuning/calibration processs for that specific vehicle's dimensions and layout.

Front radar calibration is not a new problem and is well understood in the auto industry.

These accidents really raises the question, assuming they do have a front radar, what is Tesla doing so differently that allows a competitor entry-level AEB system to outperform them?

To me it seems that NHTSA, TUV, etc. should ban Tesla's auto-pilot on public roads until they can show evidence of their safety.

They do have ultrasound (12 sensors they claim), but that doesn't help for detecting static objects iirc.
