Actually, when I asked that, I was thinking of something that happened to me yesterday.
Not to hyjack your thread, because it's not about giving up seats, but rather what I consider one sided privileges.
It's about bicyclists.
I'm going to preface this with saying I have every respect for those that travel that way, the same way I have respect for people driving vehicles. I also understand some people can give them a hard time, although around here it's less and less.
The thing is, they are all supposed to obey the same rules of the road as drivers. A lot of the time though, many want the benefits of the rules, but don't follow the ones that are inconvenient to them.
I've seen/been part of the following many times, but yesterday was the first time I ever said anything. It's a pretty typical situation.
Adult cyclist is driving down middle of car lane, as there weren't any official bike lanes on this street (my street, a side street). I was right behind him for a bit, and cars were getting backed up behind me. He finally moved over to one side, and I was able to pass, then came up to a 4 way stop. When I stopped, he just breezed right through without slowing, putting himself again in front of a line of cars. This time he stayed to the side, so we were able to pass. I turned into my driveway, and got out, checked the mail, and right then he was passing my house. "Excuse me. Can I ask you something?" He smiled and pulled over. I was super polite the whole time. I asked him if cyclists were supposed to follow all traffic signals. He said "Oh yes, of course we are" Then I asked him why he didn't stop back there. "There was a stop sign?" Yes...a four way stop. "Oh....I did see it, and yes, I should have stopped....it was just that I....well I was watching out for the other cars" You mean the other cars that were all stopping at the 4 way stop? "Uh yes..but you see..." But you were fine with cycling in the middle of the driving lane, slower than the cars would normally go, with us behind you, but you weren't ok with stopping. I'm just trying to make sense of that, because I'm aware you're smaller and I don't want to hurt you, but you expect cars to make concessions because you don't want to stop.
He took it well. Admitting he should have stopped, but no more. I think he was surprised someone actually reminded him it's not all about the cars looking out for him, but him looking out for us, and himself.
I was aways afraid to say something when this type of thing happened (a big one is a bike holding up traffic, then when coming to a red light, they bypass all the cars in front of them and get to the front of the line), thinking I'd immediately be labled one of those anti-bicyclist people.
Like if that lady responded by moving her bag passive aggressively, I'd just take the available seat that was mine to claim, and not pay her a bit of mind.
