nothing unless the hit break while the car is moving
When the speed of a vehicle doubles, the braking distance is increased by approximately four times. This is because the braking distance is directly proportional to the square of the speed.
The speedometer on a vehicle shows the instantaneous speed, which is the speed of the vehicle at any given moment. It does not display the average speed over a period of time.
Photo sensors and chronometers are used to check for the speed. The vehicle breaks the photo sensor beam, and the chronometers record the speeds.
Yes, the parking brakes can be used to stop the vehicle in emergency. But remember that, in most of the vehicles parking brakes apply only to one pair of wheels, so if the vehicle is in high speed, one has to apply them carefully and save the vehicle from skidding.
Braking reduces speed.
In practice, It is acceptable to increase the speed of your vehicle over the legal speed limit to pass or overtake another vehicle. Legally, it is not permitted. If the other vehicle is already at the speed limit, you should not be passing it. If it were a police car you were passing, at any speed above the speed limit, they could stop you.
The VSS (Vehicle Speed Sensor) moniters the speed of the vehicle.

If a vehicle's speed increases, its stopping distance will also increase. This is due to the kinetic energy of the vehicle increasing with speed, requiring more distance and time to bring the vehicle to a halt.
its mass increases as per Einstein's relativistic variation in mass...
