I don't want the noise and I don't agree it's necessary. A claimed 0.08 seconds improved reaction time (were you implying that was a lot? because a slow-moving car doesn't go far in 0.08s) is not enough reason in my opinion to have what are bound to be deafening beepers everywhere. So noise! much safety! You are proposing a ridiculous noisy dystopia. Imagine a carpark full of cars loudly beeping at all times! Cars should have sensors like parking sensors for when they're moving slowly, or flashing lights, or literally any other solution than more meaningless noise in our already much too noisy environment. You are overstating the danger with your, "you only need to make a mistake once to die" alarmism.
