Cameras are only "cheap" because of mobile phone camera development, radar/lidar is going through the same process with car and mobile robotics. So the "we can train cheaply because of lots of cameras" falls down when, for example, BYD has all of its cars with lidar for ADAS but can collect the data for training as well as the vision from cameras and whatever other sensors like tyre pressures and suspension readings and all the other sensors that are on a modern car. The argument that we can make the cars cheaper in the future by not collecting the additional data now has been proven wrong by the CN and KR manufacturers. That's also independent of the whole EV side of things.
