Christ what a ****ing drama.
I would be happy as ****ing larry if a van had scraped its entire length down my car and thats all the damage there was.
There is nothing you can do, and personally, I would be inclined to side with the van driver, as what sort of idiot hangs their car in the middle of the road pointing out, neither going for it, or moving back in to let the traffic with the RIGHT OF WAY pass ?
Sorry to sound harsh, but you never should trust a white van, you know how they are driven...
If I had been be in that situation I would have either reversed back in and with a bit more patience waited for the traffic to clear, or just ****ing gunned the throttle to get out infront of the van.
The indecision in taking either one of those two courses of action is what has caused this problem in the first place.
