Here are some other things that could be automated, but would be better if the driver actually thought about what he is doing and did them himself:
Turn off the rear fog light when there is a car behind you. Actually, not turning the damn thing on in the first place would be a better idea: it is very rarely needed.
Dip your mainbeam as soon as you see a vehicle approaching you.
Remember how to indicate correctly on roundabouts
When stopped in traffic to turn right, ensure your front wheels are straight. If somebody does hit you from behind, you won't be shunted into the oncoming traffic. Having the handbrake on is also a good idea.
Slip roads: you use them to match your speed to that of the traffic you're joining. Accelerate down on-slips and deccelerate on off-slips, it really isn't difficult. Traffic in Lane 1 doesn't have to let you in!
Give cyclists room
Remember how to indicate correctly on roundabouts.
Sidelights: they used to be called parking lights for a reason! Go straight to dipped beams.
Resting your foot on the brake pedal so that the lights come on but not the brakes is asking for trouble. Even if the car behind had left a decent gap.
