Sensor based warnings for automatic cars
Would be really nice to combine the automatic gearbox of a car with the parking sensors, so if you put your car in reverse by mistake and there is a wall behind you the car warns you as you engage R. Simple to do but would save a lot of repairs.
Silly that someone doesn’t incorporate regular parking sensors with the gearbox, so easy to do too. Love the idea, bound to be realised by someone soonish.
