I always thought the speed limit was 149?
It is for me. I regularly do 130-140 on the 401 in spots where I feel it is safe. In the end, I probably average about 100-120 km/h. The key is to not act like a *********, and cops likely won't do anything.
OP, your site just lists a bunch of "facts" where you cite political reasons, and point to other states/countries. You need to approach this from an Ontario Liberal's point of view.
Right now, the biggest issue on their agenda is the economy. Perhaps tailor your proposed change in that regard?
If people could get to work faster, you would have better quality of life as commute time would be reduced, and increased productivity/economic output. If you can provide valid, scientific (i.e. peer-reviewed) evidence to back such a claim, or increasing the speed limit in general, you would have a start.
As it stands though, it's pretty useless. Raising the speed limit would only help people during the off-peak hours. For most people, commute times are the issue, not speeds. The only way you could alleviate congestion is:
1. Increase public transit
2. Widen the 401 (No way this is a good idea)
3. HOV lanes to encourage carpooling
4. Additional highways (Also not a good idea in the GTA. 407 is not useful for many because of the congestion on the feeder highways.)
Frankly, I cannot wait for the day for autonomous vehicles. Get in your car, and it drives itself to your destination. You sit back and read a book or something. Imagine if all cars were automated. There would be no need for traffic signals, as all of the cars would be synchronized so that they never had to stop and/or rerouted based on congestion. Moreover, there would be no collisions, so all of this extra weight our cars carry would be removed as there would be no need for airbags, seatbelts and crash protection. Less weight means better fuel economy means less cash spent means better economic output.
Our governments should be pushing for development of that technology. Hell, with Canada's engineering and robotics prowess, we could lead the way. Frig, I'm an engineer, I should do it. Could start with RC cars just to get the software going. Leave automating an actual car to other people.
