Does anyone have regrets after ordering their Model 3 with FSD? Not price, but functionality. 1) Can you see the stop light status on the center display yet? 2) Is the lane change logic very safe? Does it see motorcycles quickly enough? 3) Is the summon useful? And any other thoughts? I'm primarily considering it as a safety system for blindspot monitoring (auto lane change) since the mirrors don't light up. They would only demonstrate it on the Model S, and only with the salesperson driving, so I have no point of reference for it.
