Speed limits are too low. Unless speed limits are reset to more reasonable values the "you chose to break the law" argument holds absolutely no water with me. 
I agree and disagree. The speed limits are ridiculous considering the incredible advancements in automobiles since the 1950's and the limits are the same, maybe even lower. BUT, the sheer amount of traffic on highways that have not been reconstructed to handle the capacity has created some serious congestion and problems where the traffic flow comes to a very abrupt halt. Driver skill has not inceased (perhaps decreased) and inattention is rampant as long commutes (thank you urbanization/sprawl) have people "multi-tasking" which is stupid way of saying "driving dangerously."
Traffic in 110 marked highway zones in Alberta flows at about 120-125. With a 1 second following distance, FORGET the average driver being able to cope with anything other than perfect traffic. ANY kind of problem or incident means a massive high-speed collision. Example? Coming home a few weeks ago on the #2, I was in the left lane doing slightly more than the flow when the truck to my 2 o'clock lost a tire, big-time. I moved onto the shoudler and braked to avoid the out-of-control pick-up and bits of flying tire. The Civic tailgating me (less than 15 feet behind me) was not so lucky as he had no time to react. Crash. Had I been 15 feet behind someone, we'd have been in the

too.
I have a feeling that if we increase speed limits with no other changes, we're just asking for trouble. However, we might deal with one collision problem: speed difference. That is the massive speed difference between the slower group and the faster cars. BUT, I suspect not. See, the "slower group" might move up to the new limit, but the "fast group" will simply increase their speed by the amount the limit is raised. People that cruised at 125 in the 110 would now do 135 in a 120 zone. We still have all the trouble, but now everyone is crashing at 135 instead of 125. Stupid.
But, we have to question the motivations of gov't officials when it comes to all kinds of things. Are red-light cameras about safety or money? When my suburb installed a red light camera it was disappointed at the lack of tickets. Instead of being happy about the lack of red light runners, it shortened the AMBER LIGHTS timing in order to "catch more offenders." Huh? Catch more offenders? They MADE offenders. It is this thinking that has me severly distrusting officials when it comes to setting traffic policy.
