Getting used to my new Performance Model 3, I have noticed that it has an amazing dynamic display of its surroundings, derived from radar and cameras, that improves with every update. Version 20.20.12 nicely sees and displays traffic cones, suggesting an application in autocross. There is probably too much delay for it to help during a given run, but the software has a complete history of your trajectory relative to the cones, thus could help you to learn and do better on subsequent runs. Kind of like an old Geez-Cube with a map of the course boundaries built in. Are there any apps existing or in development, perhaps that work with track mode, to do that? Perhaps it could also run on a cell phone to learn the track while you walk it.
