I tried that too and kept breaking the mounts. I think a problem it helps with is the impression that a bicycle is where the tire contacts that road; Somewhat of an optical illusion.

Yes, and it's exactly as useful as you'd imagine (not at all). Unless you're using a 100 watt halogen spotlight to project the light, no car driver would ever see it at speed.

That would be a squeeze, for sure! You must have remarkably steady riders and very fine surfaces on your cycle lanes.

I'd want to ride a minimum 6" from the edge to allow for potholes, crumbling shoulders, trash on the edge of the road, etc. Toss in 9" more for half a handlebar, call it 2" for fat bike tubes, and I'll take up 17" on my side of your bidirectional lane. If somebody is coming the other way with similar space requirements, we'll pass with 5" to spare. If somebody veers, we both go down.

We've got a half mile of heavily traveled city street with 9' lanes. Most of the lawn care trucks can't stay in that. I'd hate to get those guys pedaling down a narrow cycle lane towards me!

That's really going to hurt, when it swivels forward and whacks you. But I guess it will hurt less than being hit directly by a passing vehicle.

Having been a passenger in many vehicles driven by aggressive (insecure) drivers, that flag causes me a lot of concern. I can think of many drivers I know who would hit that flag on purpose, and consider themselves in the right. Hopefully you won't meet up with any of them.

I like the foam noodle, though.

That's a pretty good idea.

The one I like best has a spring loaded breakaway mount, a reflective flag, and an obvious jagged hunk of steel paint job ruiner on the end.

Let's see... spring loaded breakaway mount... and jagged hunk of steel paint job ruiner... you thought this through well... not. Look... it really isn't that bad out there. Flags don't keep drivers from hitting you. If they want to hit you... guess what. You're hit. The reason you keep coming home day after day is because you've not yet (in your life) encountered a driver that really, really wanted you dead. So why piss off total strangers for no good reason? Why? Do you think your jagged hunk of steel paint job ruiner registers at 50'?? Honestly, the takeaway of this entire thread is: vehicular cycling is not for everyone. There is no shame in admitting that you just don't have the stones for it. Take the bus... drive... anything but riding anyway full of fear and loathing. You make it bad for the rest of us. Your flags, super bright strobes and too many of them going at once at that. Hogging the lane... it goes on. Just do yourself a huge favor and stay out of traffic if the only way you can do it is to make a public nuisance of yourself.
