My 'chicken strips" are at least as wide as those on the bike of the OP. I don't care what other people think of how I ride, and I sure don't care about other riders who use the strips to judge that they ride more agressively than me, and therefore they're somehow better riders.
As previously pointed out, noobs and squids, and fools. As in, "look at the chicken strips on that guy's bike! He must be slooooow." The subtext is always "In comparison to me."
I don't ride agressively on the road, certainly not agressively enough to get up to the sidewall, not on the roads I ride. I don't trust the variability of the surface. I ride the speed limit, plus a bit. At those speeds, I don't think I'd ever need to get very far up on the sidewall at all.
I want to get up that far, I go to the track, where in general, I can trust the surface, and the other riders. And since I don't go to the track anymore, I'll ride how I
like on the road, thanks...
I've even taken lessons, with cars and bikes. The bike session was particularly humbling...those lessons taught me my own limitations, I'm not a good rider at elevated speeds in traffic, no depth perception. I didn't even enjoy following the instructor on the familiarisation lap.
Knowing ones' own limitations will keep you safer than exploring the limitations of any machine.
In my own experience, the most dangerous thing you can do on the road with any vehicle, is try to keep up with someone, who is driving a bit faster than your own comfort zone. I would guess that going out to burn off your chicken strips, in the belief that someone will see them and think less of you, would be a close second.
Over my riding/driving life, I have always been the guy at the back of the pack - you know, the one who witnessed the accident up front... I was OK with it then, nothing has changed.
Just my take on it.
