I think another important variation is the pedestrian on the corners of the Urban Bike Path. Never mind the blind idiot in the Volvo trying to make a right turn who decides that the bike lane, now that he thinks of it, would make a delicious right turn lane. Sure, they're motor scum, but they're bigger than me and the best I can do is take out my U-lock and disfigure a bumper or two. Real progress, I feel, can be made in the 'pedestrians on the corner' area.
Here is the situation. You are on your happy, well-loved bicycle, looking to cross at an intersection with lights. Up comes one pedestrian. The pedestrian invariably stands directly in front of your front wheel. Enter second pedestrian. Said pedestrian stands directly in the path of your escape route. Und so weiter, und so weiter.
Solution: new-fangled attachments on the front of a bicycle. They shall be called perhaps 'eternal footman deterrent' or maybe just 'flamethrower'. Guaranteed to clear the space in front of a bicycle quickly and effectively. Pilot light acts as a front light for night cycling.
Rant ends here. Thank you.
