Kids tend to watch the car rather than look ahead so the car arrives at the turn way too fast and its too late to brake before they realise. The sticky tape helps keep Mum and Dad's sanity while minimising damage. After a while, you use shorter lengths of tape, to let the car deslot gently if junior forgets to brake. Eventually, you won't need the tape. You may need to experiment a little to get it right, but its a much cheaper alternative to variable voltage power supplies.
