Tonight I was driving in Corvallis, OR, a cycling-friendly college town (a dangerous combination IMHO). Windy, very windy, and torrential rain. Very difficult to see as a driver.
Was spooked a couple of times by cyclists passing me, with no apparent headlight and marginal tail light. Saw other unlit bikes (this was all after dark).
I noticed how hard it was for me to make out the lines on the road whilst driving, and how the glare of headlights and taillights, and the bright advertising signs, and the constant change in lighting from moving from under a street light to areas in between.
I also noticed how my eyes (I'm 53) don't care for the new bright blue headlights, and especially the cars that either are using driving lights or leaving the lights on high beam.
I came to the conclusion that there are some times where cycling is just plain dumb. Drivers, no matter how conscientious, are going to have a hard time seeing even a well-lit cyclist in these conditions. I just scratched these weather conditions off my ride day list - even though it will impact my commute and my monthly mileage.
Sure, the right to ride is there - but even the most careful driver is having trouble in these conditions, and I couldn't help but think that the folks I saw out there today hadn't really thought it through very well.
