Driving peeves: Ignorance of the stop line. The vehicles FRONT bumper does not pass that line. Do not park your broad ass on the broad line. Do not creep a bit stop, creep stop creep stop creeep stop. Pull up to the line or car in front and stop. If everyone stopped too far back we'd all still be stuck at home traffic would be so lined up.
Trail peeves: Seeing large rocks or dead fall (that are easily moved by one person) with tracks over them. Get off and chuck the dead fall and other crap off the trail now and then. You too hikers.
Debate? Bikes are made for riding not pushing.
