Epic WTF

Well, not exactly. There's nothing inherently dangerous about cycling past a car, but there is an inherent danger in cycling past a car very closely

No, there's no inherent danger unless somebody/something else acts in such a way as to put you in danger. If there is nobody else around it's safe, hence not *inherently *dangerous.

• you keep your distance from parked cars partly to avoid hazards like doors opening, partly so that you can see more of the road, and partly so that you have time and space to react to unexpected events like dogs or children or grown-ass adults who have no idea how roads work suddenly appearing from between parked cars.
  
  

You're also expected to keep your distance in a vehicle, and it composes part of good road positioning and should be regarded as normal. Poor road positioning is specifically dangerous because it reduces your ability to react to sudden hazards (including but not limited to doors opening in your path), and it's discouraged in favour of good road positioning, which is functionally identical to bad positioning - as you still get to go where you were already going, at the same speed - but removes a component of danger.

Good points. There are other good reasons for good road positioning. It would be odd to expect kids and dogs to be aware of your safety.

That's not to say that people who open a door into somebody's path shouldn't be prosecuted, as it's still an offence.

Exactly and that's what the poster shows. So why are we not incensed that it puts the onus on the cyclist to stay out of danger, when the danger (at least as portrayed on the poster) is entirely manmade?
