If you get caught exceeding the speed limit with more than 100% the car you drive will be confiscated and sold on auction. The money goes to the government. This is regardless if it is your own car or not. It makes no difference if it is yours, a company owned car, borrowed, leased or rented. You loose the car.
The same goes if you drive very drunk or drive so reckless that your driving is being classified as "insane driving"
