In Ontario, one would likely lose the car for part of the year for a single offence of that magnitude PLUS an enormous fine. There was a time recently and in an effort to end street racing, when the car could have been crushed at Chief's recommendation and the JPs discretion, but that was repealled. 50+ kilometres over the posted limit is considered STUNT driving. Several of them became ashtrays and garbage cans. Dangerous driving offences may fall under the Criminal Code of Canada and that means that it is a criminal offence that would NEVER be expunged from your record. Never a good thing when applying for a job.
The biggest concern is the gift that keeps on giving (at least for three years) - the insurance costs! There are some companies that will deny you insurance for 3+ speeding tickets. THAT is something you never want to have. If you are denied and an insurance company asks if you have ever been denied - you sure don;t want to lie about it. One may NEVER be able to afford what they'll charge you! How about $13K annually?
Whether I am accurate or not in what I stated above, I know that it just ain't worth it!
