there's 200-300k cars out there with just cameras + radar and their bet is the software catches up to the rhetoric. Adding lidar is next to impossible on the current fleet and adds to the cost if they start now. It is an early design bet which the coders now have to meet.
Hopefully no one bought a car hoping it will magically be “fully autonomous” in the future, given that no one knows whether it will even be possible with a research vehicle in 10 years
