Considering time and mileage on bicycle vs car/motorcycle/walking, I must say I get the least road rage while on bicycle. Especially considering I do slow traffic down sometimes, drivers have to wait for a gap to pass me on some roads etc.
When I do get road rage on a bicycle I just smile: I am lucky to be able to ride bicycle, instead of the cage. I do HATE driving car in town. If I had to stay in the cage, I'd probably be pissed with cyclists as well.
Once a truck that had to wait for some 5 seconds to pass me and I made him slow down (he sat on his horn for like 3-4 seconds, but I just ignored him - he had the whole left lane as soon as the car next to him moved on) deliberately stopped some 500 meters away after passing me, waited for me to come to him and start passing, then got going and swerved onto me. I did brake on time, avoided him (luckily I gave him plenty of room when passing him, or he would have knocked me down). Since there was no witnesses, it would have been my word against his, so I just let it go. No use going to prison - too many idiots.
Another occasion was while on foot. Walking by the riverside on a MUP. A car was behind me (it is usual here to drive even cars on MUP, though it's an offence). I moved to the right of the path, further right was mud and grass. Since a bike was comming towards me, the car didn't have room to pass me. Had to wait for the bike to go past us first. So the guy sounded horn on me (I was all the way to the side of the road - only mud was further right). That really annoyed me so i showed him the middle finger. He then stopped, got out of the car: "what was that for"). I was just silent, took my glasses off and put them away. He backed up and started some blablabla (then his wife also got into argument, how rude I was and so on). I just asked him if he knew he's not supposed to drive there. And said I moved all the way to the side of the road. Said hes a rude for doing what he did. Then wife told me to **** off and they took off. After that I never try to react. For a second he was considering using brute force. It could have been very nasty situation, for no reason.
