"how they compare to Tesla" Given that Tesla doesn't even have emergency braking and auto-steering, I'd guess they compare quite favorably...
Tesla will have 100,000 prototypes being trained in shadow mode for a billion miles per year across the globe within a year. Tesla will compare quite favorably
* that road with the one-foot deep pothole (it's more like a sinkhole at that point, though) in the middle of a lane
* the perpetual construction zone where there are five layers of lane markers, only one of which is the actual layer of lane markers
* the 10% grade two-lane winding road in the dark with 2 inches of snow on the road and more coming
* open highway with a constant 30mph crosswind
* dense fog with less than 100m visibility
* torrential downpour with so little visibility you can't even see the lane markings on the road right in front of you
Those are all conditions I've driven in, and I can think of several other horrible driving conditions that I haven't yet had the (mis)fortune to drive in. Just because you can drive well in good conditions doesn't mean you can drive well when things get tougher--as the driving records of many human beings can well attest.
