Taking away someone's privilege to drive is viewed as a drastic step in correcting driving behaviour. Currently, a fully licensed driver has to accumulate a significant number of points in a year before the Superintendent of Motor Vehicles takes steps to apply this penalty. In my experience, the traffic courts are also reluctant to take this step, saying "I'll leave that up to the Superintendent." when the officer prosecuting requests a prohibition as part of the penalty.
Paul Hergott is a traffic safety advocate that regularly writes about traffic safety. He's observed that the IRP has made significant reduction in incidents of impaired driving death and injury. In his article Raising the Level of Consequences for Bad Driving Choices he suggests that the IRP should also be applied to drivers who cause a crash, regardless of the level of severity. Getting that licence back would require taking driver training.
Perhaps this would be an incentive to drive in a responsible manner.
