Is this really all that important? There are 3 other cars ahead of the Tesla at this red light intersection. If you're able to react within tens or hundreds of milliseconds to a changing environment, it would actually make sense to reduce compute to save power for when the vehicle is in motion and not surrounded by other vehicles at a stop light.
Edit: It seemed to handle that intersection just fine, but a couple of turns down it ends up on the wrong side of the road, which is quite bad. That said, what proof do you have that Waymo/Cruise would be any better at this?
Here's an hour of a Cruise vehicle driving in San Francisco.[1] Watch it deal with a trash bag that fell out of a dumpster, a left turn across heavy opposing traffic, double-parked cars, cars pulling out of parking spaces, a FedEx truck changing lanes across their path... Makes Tesla look like amateur hour.
Since they rely on pre-mapping, that’s the equivalent of a carnival ride on rails and not really comparable to what Tesla is doing (unsupervised training on billions of unknown road miles).
Being able to detect oncoming traffic seems pretty damned important to me! If it’s not detecting vehicles across the line, what assurance do I have that it’ll detect vehicles that cross the line?
