They already evaluated retrofiring sensors. Doing it would cost about as much as a new car. They've made a bet that this sensor suite will be enough and I'm sure Musk got green light on it from his team. Time will tell if they were right. I personally agree with them that technologies like PseudoLIDAR will be sufficient. I believe that for a good human driver Tesla sensor suite would be sufficient to drive safely if you covered all windows. You could project the camera views on covered windows and keep the current bird eye visualization. The issue really is with control of the car. Deep Reinforcement learning sucks. Training Deep RL is unstable, hyper-parameter sensitive, even random-seed sensitive, and requires ridiculous amount of data for even the simplest applications. And after training it does not generalize.
