Have to say it again, that's pretty rare. I personally have never seen 6 bikes riding abreast. Was this in Ballard? 10 mph is pretty slow for a bike too but I do see bikes go that slow and I am always mystified why they don't ride on the bike path as they are usually near one.
As far as passing, I rode around Mercer island yesterday. I'm in the twistys area doing a bit over 20 mph, which is way too slow if your driving but pretty decent on a bike. Car comes up behind me and slows down. I stay to the far right sometimes inches from the gravel, they don't pass. I keep going road is straight, I am as far over and going as fast as I can now, up to maybe 24 now, still no passing. Plenty of room to pass. My guess they just didn't want to pass. maybe they just wanted to look at my ass, I hope not....
But the moral of the story is that some people just don't want to pass. A light tap on the horn never hurt anybody and I appreciate it if someone does that to signify their presence. Did the riders actually know they were holding up a car? I really see very few things like this on the road. I had maybe 4 cars buzz me yesterday and a guy turned left directly in front of me and I know he saw me, passing well within 2 ft at approx 30 mph. Oh well,.... they didn't kill me and if I get mad I will end up staying mad for an hour about it over nothing I can do, so I just let it go.
Overall here's the deal, I ride alot and give cars as much berth as possible always because well, I will never, ever win an argument with a car, but there are crazy people out there all over the place. Some drive, some ride bikes, some walk. I really don't think it does much good to accentuate the antics of the small percentage of goofy riders out there.
Lets talk about the groups of people who walk 5, 6 abreast down crowded mall walkways now....
