I am not sure if this has been brought up before...but I am awaiting a Model 3 AWD this fall (before the credit gets reduced ) , and my son who will start driving in February when he turns 16. I read somewhere there was a speed limiter option in the app now, perhaps for the Model S, but what I am thinking goes beyond this. I would like the ability to SLOW the car down, based on driver profile (or perhaps even a guest driver with just the card key) so that it: 1. can't go over a certain speed I set - say 75 miles an hour and 2. the 0-60 time is slowed...so maybe it only goes 0-60 in 6 seconds. Both of these settings would minimize issues, such as excessive speed or multiple attempts to launch the car as fast as possible. I know the 3 AWD is not as fast as the Performance 3 or a Model S, but it still is fast enough to encourage romping on the accelerator pedal....by a kid, valet, or anyone else that might borrow the car. With this, we can be in control of who really gets to have fun!
