Personally I think track drops don't do a single thing right for street riding - there is no flat portion to ride (so you have to grip right near the stem), the bends are too severe to grip well while climbing and the drops are too deep for most street riding. I think 9 out of 10 people using track drops on the street would be better served using road drops. Hell, I use road drops on the track!

That said, I don't begrudge people who ride track drops on the street, so long as they are at the very least plugged. I wish more people would wrap them (and wrap them properly - how many times have I seen track drops with only the drops wrapped when the rider is never in them, or when only the tops are wrapped - suggesting that the rider never uses the drops).
