In most cases, cyclists are more than willing to accommodate drivers - it's in our best interests as even the slightest contact with a car can lead to serious injury or death. All we ask is for drivers to keep an eye out, give us space, and not try to kill us to save a few seconds.
Like most drivers I've had experiences to suggest otherwise. It's my sense that a fair number of cyclists feel an entitlement to the road, not just to safely sharing the road with other vehicles. I'm fairly sure - my own assumption - that some cyclists feel themselves superior to those driving carbon-burning cars and enjoy strutting it.
Once saw a cyclist heading in the opposite direction to mine, very heavy traffic in Toronto, traveling in the middle of the lane, arm raised high with finger extended, followed by about fifteen cars, a third of them leaning on their horns. He'd certainly been doing that for a while.
Once encountered a cyclist myself, quiet country two-lane paved road with plenty of paved space to the right of the solid line defining the lane. Cyclist was again driving in the center of the lane, well below the speed limit, and I had a double line so could not pull out to pass him. My horn got me his one-finger salute too.
Riders riding in the driving lane - though not in the middle of it - when there's room for them to ride the white line or even outside the white line is a very, very frequent occurrence. Many times I've seen riders traveling side-by-side in Ontario, many times. I've seen them three-abreast occasionally, again occupying far more than their share of the road.
Then there's the guy I came within inches of hitting last year, at night, dressed in dark clothing without reflectors, no lights, two feet into the driving lane... If there had been another vehicle in the opposite lane preventing me from swerving violently to avoid him...
I'm sure that many cyclists are not like these; maybe even most of them are not. But these are the ones I remember when people are talking about cyclists' rights and restricting arteries for bike lanes and other changes that make driving harder and slower and more expensive while accommodating the small minority of people who even WANT to cycle for anything but recreation.
