Do you think spending money on limiting production cars (electronically by computer chips) to 110 kilometers per hour (or whatever the speed limit is). Those in need of a speed burst because of emergencies or whatever can push a button on the steering wheel or press the accelerator twice in a row really quick, but doing so causes the computer chip to record the action and broadcast it to police offices or whatever (you get the idea dammit... )Besides the money, I do not see many cons to this idea, and it is quite simple as well. However, it still can not stop motorists from speeding on regular roads where the speed limit is around 60 kilometers per hour.
Of course, removal of the chip would be illegal.
EDIT: please give me some bad effects of implementing those rules.
