This past weekend my 17 year old son was planning to attend his senior prom with some friends and asked me if he could PLEASE drive my Model 3. After some consideration and a thorough review of his plans (who will be in the car, where will he be going) I agreed. Before he left I enabled the "Speed Limit" function with my phone and set it to 60mph. His route would take him mostly on country roads with 50mph speed limits. This was the first time I've used this feature. He was totally fine with this. Until he realized that it also set the acceleration to "Chill" mode. He asked me to remove the limit so that his friends could experience the 'awesome' acceleration of the Tesla. I thought about it for less than a nanosecond and said "No." Senior prom is exactly the wrong time to be giving demonstrations of Tesla's performance capabilities. Even in chill mode, it is no slouch, its just not Tesla fast. The mobile app that provided updates on the speed and location of the Model 3 were nice. He spent the night at a friend's house (per plan) and returned the next morning. He was grateful for the privilege of being allowed to use the car and in hindsight agreed that having the car in speed limit mode was a reasonable decision. Thanks to Tesla for making a car that is nice enough that my son is eager to use it, and for providing me the ability to tone down the performance enough to make it a safe car for it to be loaned to him.
