The difference happens when you&#x27;re involved in an accident, i.e. when personal or financial harm is involved (insurance etc). While there is an amendment stating that a suspect cannot incriminate him&#x2F;herself, I don&#x27;t think it applies to a traffic accident (where the car is impounded and its data read for information that could previously only be gathered by looking at skidmarks and the like).<p>Automatic fining, best not, but alternatively as a driver you should be able to automatically limit your speed, especially in a car like the Tesla where speeding is very easy.<p>Wouldn&#x27;t you agree that preventing an accident is better than finding out who is to blame, or survival chances, etc? Speeding is still one of the main causes of traffic accidents, and even if it&#x27;s not the cause, it&#x27;s the primary factor in the amount of damage caused.
