Tldr
like every heavy commercial vehicle on ontario roads already are?
That was a shortsighted heavy handed government approach to solve a problem of ****** undereducated reckless drivers in the industry. Did it work? Arguably, yes, although now the ****** undereducated reckless drivers perform their idiocy slower.
The non-commercial driver crowd in ontario cheered this at the time, but hey, now people here complain about those evil slow trucks trying to pass each other.
So, moral of the story is be careful what you wish for. The idiot behind the wheel is the root cause of that sort of knee jerk reaction. They are the "stupid" variable. Virtually every econobox cage on the road made in the last 20 years can reach speeds sufficient to yield a stunting charge but we all know that the average driver never reaches those speeds, yet reading enough threads here quickly makes it obvious many cyclists do...often routinely.
When end a few idiot truckers acted like idiots next thing you know we all found ourselves electronically governed to 105. And there was much rejoicing outside the industry.
Hope it never happens to bikes, but there's always that stupid variable.
