How would you get out then? Take a guess and go? Take a leap of faith?
There is no way you can get out of a turning where cars are parked blocking your view other than to slowly edge out whilst constantly looking left and right.
It is my opinion, and it is just an opinion, that if you have to edge out and are stationary whilst hit then how can it be your fault? It is also my considered opinion that the drivers on the main road were either blind to the OP's predicament or being rude and ignorant at not giving way to her
Isn't there some road 'law' whereby you can behave in such a manner that, although you may have right of way, you could be accused of being the cause of an accident and therefore the guilty party? Can't think of the phraseology right now. For eg, if you come across those cones on the motorway but refuse to let a car pull in because you think he is being cheeky and if he hits you or the cones it could be deemed your fault?
