Mercedes becomes the first automaker to sell autonomous cars in the U.S. that don't come with a requirement that drivers watch the road

Drivers can activate Mercedes’s technology, called Drive Pilot, when certain conditions are met, including in heavy traffic jams, during the daytime, on spec ific California and Nevada freeways, and when the car is traveling less than 40 mph. Drivers can focus on other activities until the vehicle alerts them to resume control. The technology does not work on roads that haven’t been pre-approved by Mercedes, including on freeways in other states.

Meanwhile Teslas with FSD V12 drives just fine in just about anywhere, including roads that aren't even mapped.
