"Drafting mode"—an easy & safe way to increase highway range

On a few long trips in the winter when range has been an issue, I've followed semi trucks at a safe distance. This can dramatically increase range for a given speed of travel by cutting down on air resistance.

The problem is that enhanced autopilot doesn't work well for this, because it always wants to change lanes to go slightly faster, and doesn't automatically follow the semi in front of me when *it* changes lanes,... more »

Autopilot Modes: Chillax Mode

-speed limit setting is more of... more »

Option to disable TACC use "dumb" cruise control instead.

I would like to have the option to disable TACC and use "dumb" cruise control instead.

I have experienced horrible ghost breakings. Suddenly middle of an empty road the car slammed brakes for 1 second and continued forwards. There was absolutely no reason for this breaking. If a car would have followed me it would have caused a rear-end collision.

Tesla give us the option to go with "dumb" cruise control, please.
