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).
