As a law abiding cyclist who commutes everyday on the road, I'm VERY disappointed by Professor Caldwell-Harris' remarks: She implies that it is physically hard for a cyclist to lose his/her momentum, and thus the behavior of running through red light is justifiable. Sorry if this sound harsh, but THE WEAKNESS OF ONE'S MUSCLE OR GEAR-MANAGING TECHNIQUE DOESN'T JUSTIFY ONE TO BREAK THE LAW. As a law abiding cyclist, I found myself being respect all the time by the local motorist (and was first quite surprise for that). In fact, in the last 4000 miles of bike commute, my ONLY accident was caused by a law-disobeying cyclist who rear-ended me when attempting to squeeze pass me on the right. By breaking the law constantly, YOU are making yourself a second class citizen on the roads. I sincerely hope that Professor Caldwell-Harris can take the initiative to encourage motorist to share the road by obeying the law, instead of giving biased justification of law-breaking unpredictable behaviors.
