Answer 1

It is for safety reasons for children so that they wont hurt themselves.....

Answer 2

I dont know in which cars you have this, since i havent seen ANY car with that, but it is simply to cut production costs.

If you install 4 electric motors or 2 electric mortors, which one do you think costs less? The 2 electric motor option. So, to save money, the company puts less in the car.
