My issue with bicyclist is the disregard for other traffic out in the country, where they transform from slow traffic into traffic obstructions, riding 2 or 3 abreast on a 2 lane road at 10 mph, while you and oncoming traffic is travelling at 60mph..
Meet on coming traffic at 60mph on a corner, and it's no issue.. Stick 3 idiots on bikes at 10mph in the middle of that blind corner, and someone's going to get hurt!! Can't stop in time for the human slowpokes and can't swerve into the oncoming lane because there's traffic there..
This happens all the time around here.. Groups of 30-40 touring bike riders riding down the middle of the road with no thought of the fact that all other traffic around them is travelling a 6-10 times the speed they are.. It's inconsiderate, and dangerous for everyone..
Hell, I don't ride my 150cc scooter on busy roads because I can't keep up to traffic on hills or into wind, since it only will do 45mph in those situations, but it's OK for a bike rider to do 5mph in the same situation and take up an entire lane while doing so??

And don't get me going on the fact that stop signs have no meaning to them, either.. It's like a bunch of Harley riders in a parade.. The only rules than they obey are what they want to.. The rest don't matter??
I have no issue with bicycles operated in a safe manner, out of high speed traffic, but when they become careless traffic obstructions, I think they should get a ticket just like anyone else would.
