This is one of the most asinine statements I've ever read.
The number of sensors is not how you determine if a car is autonomous or not.
All the autonomous cars we've seen so far from the main AV companies all have more than just 2 lidars. And they have radar and cameras too. So I don't think it unreasonable to conclude that it is probably not an autonomous car from one of the main AV companies. Perhaps it is an autonomous car from a different company that we've not seen but the main AV companies don't use just 2 lidars for their autonomous cars. IMO, it makes more sense that it is probably a mapping car.
