Why is a very large deceleration dangerous for a vehicle?
The brakes can overheat and the driver may lose control of the vehicle
The thinking distance becomes much longer than the braking distance
The mass of the vehicle rises and the brakes then become less effective
The vehicle travels a greater distance before it comes to a full stop
