My point is... if such a law DID exist... I suspect we would have a WHOLE LOT LESS repeat offenders roaming the streets...
Yes, I agree - there would be a lot less repeat offenders roaming around.
For a younger offender (say 18-20 living with his parents) probation is a way not to let a youthful mistake ruin his whole life. The idea being "Look numbnuts: you've been given a second chance to behave yourself SO DO IT. Some would be thankful for the second chance and use it to become constructive members of society. This dumb ass used it to kill three people and ruin a fourth's life forever. He should now go away for a long time.
Even top race drivers sober could not drive along a city street like Finch, York Mills, Steeles etc at 200 km/h safely. The streets are not in great shape - potholes, uneven pavement, road debris, cars emerging slowly from side streets, left hand turns, pedestrians...heck, people's driveways back out onto Finch FFS. If one hit a pothole at that speed one could easily lose control and go careening into pedestrians on the sidewalk, somebody's living room, etc. It isn't a case of he was driving fast while sober in the middle of the night on an empty stretch of 407. To do what he did was a total negligent disregard for the lives of others, where someone's death was not just a risk but was the
probable outcome of his actions.
