I've had several people either fling open car doors or park on double yellow lines so they can use the postbox then simply fling open the car door regardless of who's coming towards them, in this case i use the horn and door skimming technique.
Yeah, I think these people deserve to get their doors taken off. The orst ones are the people extracting their kids on the road side of the car in rush hour. Yes, I can imagine it's a logistical challenge but I'd rather be leaning over the back seat from the safety of the pavement and get a bad back than risk my own and childs life like that.
I don't see how any of the blame could be on the person who hits the door unless said driver is proven to be speeding or not paying attention.
