Of course they are, but if you wear gear and don't ride drunk then they go from being an order of magnitude more unsafe to what I would consider a mitigable risk. My point was more that society's prevailing attitude is one of placing blame on prospective victims than punishing conspicuously-bad driving. Small cars are probably a more casually-defensible case since we both mentioned them.

In my experience this is rather unusual. I've only ever seen lane restrictions for trucks and even then it's usually for actual trucks, not the quarter-ton luxury family haulers that have emerged over the past 15 years.
