Brakes systems in vehicles, such as for example cars, have reached more or less the maximum possible efficiency within the normal principles of braking, which are based on applying a strong and efficient force on the vehicle's wheels. Therefore, the wheels can be almost instantly stopped, but the problem is that the next weak link is the friction between the wheels and the road, so that for example stopping them too fast can cause skidding. In order to prevent skidding, ABS (Anti-lock Braking Systems) were introduced, based on a computer chip which senses when a wheel is locked up or is about to lock up. However, recent studies by insurance companies showed that there was no substantial difference in accident claims between vehicles equipped with ABS and those without ABS. Other systems have already been proposed for improving the human perception time and/or reaction time by using some automated system that can detect an imminent collision for example by sonar and thus for example warn the driver or automatically engage the brakes. The present invention shows solutions that reduce further also the braking time of the vehicle itself - by using a novel principle for stopping the car that is not solely dependent on stopping the wheels. This is done by using another force that reacts directly with the environment, preferably in addition to the normal braking of stopping the wheels. This can be done for example by using a jet of preferably pressurized air that creates an additional thrust against the movement momentum of the vehicle. This way this can also help prevent for example skidding, since it is an additional direct force against the environment. Other possible variations are for example using some solid object that reacts directly with the road, such as for example some high friction anchor that can be dropped down, preferably automatically, in an emergency stop, or for example additional wheels with preferably very high friction which can be dropped down, preferably automatically, for emergency breaks.
