Speaking from personal experience, as a driver I absolutely hate cyclists. Weaving through traffic at speeds slower than the vehicles they cut off, no indication of intended lane changes, running of compulsory stops, shortcuts across footpaths only to pull out in front of vehicles that have right-of-way. I've seen them push their bikes through red lights, to avoid the "but you rode through a red light so you're in the wrong" legal consequence they might face if hit. There was one group of adults and children who overtook me on the side I was indicating and moving to turn, once. That's most illegal here, and I nearly hit them. (They blamed me, but the police blamed them when I phoned the complaint in. "If you ever see that again, have your passenger phone us and you follow them, so we can have a chat with them about safe road use.")
Then there are the times I was a pedestrian. I've been crossing the road at a controlled intersection at one particular location for several years, and in that time I've nearly been hit by a car once. I'm nearly hit by cyclists running red lights there at least once a month, usually a lot more often than that.
One particularly stupid individual on a bike was doing about 45mph on the footpath, cutting blind corners very closely. Nearly hit me three days in a row, and if he had I would have been hospitalized just because of the speed he was doing - stupid little %@#! went on Facebook and started bitching about how a pedestrian had been in his way, I later heard, even though he was riding illegally.
Another one - who should be nominated for an honorary Darwin Award - was trying to squeeze between two parked buses. Had my friend (the driver) not noticed, the cyclist would have been crushed to death.
Why do I hate them? Unpredictability. Many of them are car drivers (weather extremes in my town make year-round cycling a rather miserable affair) who know they shouldn't be doing these things, but they don't care because how will anybody track them down if they don't have plates?
I'm not going suggesting that all cyclists are like this by any means, nor am I going to get into drivers because that would be off topic. I'm simply trying to add a little perspective as to why drivers may dislike cyclists. I am very much in favor of physically separated spaces for cyclists (although how controlled intersections would work is a topic I leave for civil engineers and law enforcement).
