Even though it was initially rejected, getting this kind of attention does show it is on the right track. The Liberals are currently against it, but if enough people speak out about it, they have a change of heart (after a face saving "study," of course). Even then, keeping up the noise could have this become an election issue, where an opposition party may take side and use it as a hook to attract voters.
From what I've heard, in most places in the US they tend to start ticketing after going 10mph (16km/h) over. Even here, though you are generally safe from enforcement when driving up to 20 over, at 16km/h is when you become susceptible to demerit points. If the speed limit was raised to 110km/h, with ticketing starting at speeds above 120km/h, the flow of traffic would be safer since there would only be a difference of 10km/h between the fastest and slowest cars compared to 20 like there is today.
Being realistic, while it would be great to see speed limits of 130km/h+, I don't think that is going to happen on the first swing. Let's get it up to 110km/h first, and go from there.
