I am going to take some crap for this one. Not many but a couple people.
I am a considerate driver when it comes to people on bicycles. I think that it is a great way to exercise and a wonderful alternate form of transportation. I make sure that I don't tailgate them on back roads. I pass them carefully if needed, I don't gun my engine.
So when some jackass who thinks that he is Lance Armstong or just has his ego, decides to flip ME off for cutting me off in an intersection when I have the right of way (see that left turn signal, buddy it's for people make LEFT TURNS, NOT GOING STRAIGHT!) I get really fired up.
Who do these guys think they are? They are on a moving vehicle which is subject to all the traffic laws that we in cars are supposed to abide by but they are almost NEVER ticketed for things that would warrant HUGE fines for drivers in cars. They blow stop signs, red lights, use turning lanes as their own personal line jump at traffic lights and are a generally selfish bunch.
Share the road? Yeah, I'll share the road when they decide to share it.
No excuse for this kind of behavior at all.
