>If I'm in reverse for example I lose all ability to adjust the temperature, fan, or seat temperature

For every single millisecond after you check your backup camera to make sure there's no kid in the blind spot behind your car, your whole-ass body should be rotated with you head looking over your shoulder and out the rear window.

Unless you have a monster SUV that you can't see out of anyways, in which case use the screen.

In either case the driver should be spending an exact and precise 0.0% of the time a vehicle is in reverse manipulating any control not related to steering and acceleration.

"But what if the passeng.." Don't. Please don't.
