Although, autopilot or not, I hate the herky-jerky way that some Teslas users manually drive. The "your either slowing down or speeding up" pedal philosophy inherent to Teslas isn't considerate of others on the road, and there are few things as obnoxious as a Tesla in front of you gradually slowing to 5-10 below the speed limit and then blazing forward at 20 mph over the speed limit.
Too slow AND too fast is a terrible combo.
