Rant
As someone who used to bike a lot (a whole heck of a lot) it kills me to see cyclists on the road doing dumb a$$ things. It puts all cyclists in danger further down the road, not just the DA one in front of you.
Remember, this is coming from a former cyclist who raced competitively. A few years ago in Travelers Rest I was stopped at the light beside McDonalds going across to the WalMart side. A group of about 15, maybe more, cyclists came up behind me when I was the only car stopped at the light. They were in a pack in the middle of the lane which was a good way to ride at a stop light to cross a busy intersection as a group for protection. Bikes don't have bumpers so any collision between a vehicle and a bike, no matter who is at fault, is going to be lost (very badly I might add) by the cyclists. Riding en mass like that makes it easier for the group to be seen, and hopefully not hit by a vehicle.
So DA #1, 2 and 3 (all appeared to be teenagers and the youngest in the group), decide to ride past me and get in front of my vehicle, effectively splitting the cyclists group. This mean they 3 bikes in front of me would slowly cross, I would have to put along behind them, and then the mass group of cyclists would have to cross behind me = bad ju ju. I put the vehicle in park, and lectured them like they were little children who spilled their milk on purpose. I berated them about how dangerous they were acting, and coming from another cyclist, they were putting every other cyclist on the road in danger. I usually don't pop like that but I did. The adult cyclist in the rear of my vehicle then joined in with me and made the youngsters return to the pack. At least the youngins hung their head as they rode back past me and apologized. The light then turned green, I crossed, and the pack of cyclists crossed together en masse, safely.
And I don't give a rat's patookie if the officer was worried about what the students would 'think.' Now the students think it's OK for a cyclist to break the law, be a DA, and it will always be the driver's fault.
