What I said before ... it's got little to do with absolute speed, and everything to do with relative speed among road/trail users.

10 mph is TRIPLE the average human walking speed, and FIVE TIMES what children and mobility-impaired adults - the kind of people you're likely to find on a MUP - are likely to be doing.

Just as there's nothing inherently unsafe about driving your car at 120 on an empty piece of straight, flat four-lane out west where there's not another car for 100 miles, there's nothing inherently unsafe about riding your bike at 20 on a MUP. The trouble comes when there's other traffic.

Sure it burns me if I get a ticket for speeding in my car or bike when it was obviously safe to do so. But I eat it, because them's the rules and they got me fair and square. It would burn me if I got a speeding ticket on the bici when it was obviously safe to do so, too. One thing missing from the OP is whether or not there was any other traffic. Another thing missing from the discussion is that the cyclists in question were ticketed for doing TWICE the limit and a speed that IMO should just not happen on a MUP.

This goes back to the discussions about the penalties when automobile drivers kill bicyclists, too. I've been thinking a lot about that and the position that a few here - and most automobile drivers - take, that it's "just an accident." Actually, I tend to agree ... if people are doing stuff in/on their vehicles 24/7 that makes it just a matter of LUCK that they don't kill someone, then when they DO kill someone, well, it WAS just a matter of luck, and that's why so many people think they shouldn't be punished for it. The problem happens way before that, when they decide to take their chances with other people's lives.

They ... WE ... should be punished severely when we take chances with other people's lives. Not only when other people lose the bet that they didn't know they were making with us.
