>The fact is that these existing services are extremely constrained in terms of geography and operating hours (though the latter is arguably a regulatory issue) Is it though? Cruise would like you to believe that the only reason they don’t have fully driverless cars in SF during the day is strictly regulatory. However, it is far easier to drive in a dense urban environment at night when roads are empty than during the daytime when roads are crowded. I bet the disengagement rate is so high during the day (when the cars have backup drivers) that fully driverless operation would be impossible.
