Interesting write up contrasting Waymo with Tesla:
Tesla Robotaxi vs. Waymo vs. Cruise: Here's How They Stack Up
- the former have lots of sensors and rely upon very detailed digital mapping
- the latter rely principally upon cameras and AI scene analysis
Even with detailed mapping, Waymo must still be able to cope with the actual road layout, weather conditions, changes to signs etc etc. The actions of other cars, vans, cyclists and pedestrians etc are unpredictable and cannot be mapped anyway.
Tesla have a higher accident rate and Elon is prone to glossing over a lot of the technical detail so one can never be sure that it is the "truth and whole truth".
The Tesla approach if it can be made to work properly seems the better solution long term, and broadly replicates what we humans do - being equipped with sight and sound detectors, but few of us have radar and ultrasonic sensors!
