Really? Last time I checked, all those drivers who speed haven't been locked up for life and they're certainly a danger to society. Though prison might be too hot for them with all those dangerous marijuana smokers which the justice system has availed of us
Is it? In which case should the penalty for all offenses be the same?
Regardless of that: if the goal is simply to get these people out of circulation, anything that makes that process easier / cheaper is presumably worth it. This change goes the other way.
