### Comment:
You're talking about a different problem. My point was that LIDAR, dedicated lanes with sensors, or some other expensive solution, won't meaningfully contribute to a computer's ability to anticipate other drivers' movements, read signs, etc. The cost doesn't justify the marginal performance gain.

### REPLY:
Sort of. Lidar can allow you to build an exact replica of a scene inside the computer, so that if the computer does an error, it can generate training data by repeatedly simulating the same situation until it gets it right. 
  
 Tesla could do this, but far less reliably with machine vision. They need far more training data. Good news is that they have way more cars on the road, so they have more training data.
