There is a driving technique that would be very helpful here. Not only for Tesla, but for all non manual transmission cars. Learn to use your left foot on the brake pedal. When I pull into a parking spot I hover my left food near the brake pedal. I seldom need it, but the reaction time is much better than right foot off the accelerator and on to the brake. The reaction is left foot down, right foot up and off the accelerator. I've driven this way for years. It is very useful when you are in a driving situation where you think quick braking might be necessary.
