If I'm driving, I'll block the shared bike lane on a right-hand turn when I'm close to the intersection to prevent a cyclist from passing on the right.
The example degnaw gave is more of what comes to mind. Getting blocked at an intersection when a car is turning right happens when I'm in a car as well, so it's not something that I think of as hostile.
Whether it's right or wrong, a simple reality is that "having to pass" the same bicyclist is something that irritates lots of drivers.
Personally, I never go to the front of the line unless its on the shoulder.
I understand this sentiment, I hate having to pass the same cyclist even when
I'm on a bike, but not because of actively having to pass, rather that they blast through red lights and stop signs. If that's the reason then her irritation is warranted, but her actions to actively block are not.
Personally I love my car and I'm a former car enthusiast/hobbyist. There's no way I'd risk my car getting close enough to have a cyclist's pedals or handles scratch my paint job, not worth it.
