2 things: 1) I drive every kilometre of the 400 series within the GTA, and also the DVP, Gardiner and QEW, every so often and I can do 130 over every bit of main freeway laneage if I so desire, congestion and weather permitting. Except portions of the DVP & Gardiner. It "can" be done, but definitely some sections requiring extreme care.The eb409\401 entry ramp is also an exception, but that's a ramp for all intents and purposes. On the 407, 130 isn't even enough to stay in the left lane. On that hwy I tend to stay in lane 3 from the left except to pass (in the wider sections).
2) The number one issue I observe is the left lane hogs doing 95km/h. A lot of congestion, faster-moving vehicles weaving in and out of the non-left lanes and such are directly caused by slow movers in the left lane. I can't tell how many times I encounter "crowded" conditions on these hwys, only to discover at the head of the line are a bunch of vehicles all lined up beside each other doing the same speed across all the lanes and therefore not allowing anyone to pass. Sometimes, if I'm especially annoyed, I'll do this: once I'm finally ahead of the left lane slow mover, I'll get in the left lane and gradually slow down in front of them to the point where they are forced to move to the right looking to get past me, then I'll speed away and watch as piles of cars looking to get by pour through the opening I've just helped to create. And how often do you see the left lane hog driving with a death grip on the steering wheel, as they are clearly unable to deal with the speeds that are expected when in the left lane, but won't move over?
We need to more strongly enforce the left lane rule here. In the US, you can't cruise in the left lane. Do it long enough and you run the risk of being pulled over. The left lane is to be used as a passing lane. Cruise on the right; when a slower vehicle is encountered, switch to the left, execute the pass and then get back to the right. It's been posted here many times that we should also change those "slower traffic keep right" signs to "keep right except to pass" signs. Better wording that may help to keep the left lane more clear.
The HOV lane being the left-most lane confuses the issue, as people now thing they can cruise in any general purpose lane, but by hwy etiquette, the left lane should still be the fastest moving lane, as each lane to the left should see an uptick in general speeds, similar to the visual example shown above.
I, for one, am there for autobahn-style rules, where the right lane is regulated, moving left speed limits go up and the left-most lane(s) is/are no limit. On the 407, which is the closest thing we have to sane driving locally, in that drivers get it pretty quick not to lollygag in the left lane(s), as folks are over there regularly doing 140+. The 401 express/collector system is actually well-suited to a structure that could state limits of 120 km/h in the express and 100 km/h in the collector.. And yes, for kicks, I occasionally drive across Toronto in the collectors only and it's quite doable in the left 2 main lanes without having to do much lane changing (for lane alignment reasons, anyways)..
