Delphinus: Had a moment this morning where I was stopped at a give way. Car approaching from the right indicating left and slowing down, starting to turn into the road I was coming out of. I checked left, lifted my foot off the brake to pull out and then suddenly the turning car is going straight through and not turning any more! The driver looked lost. Who would have been at fault there in the case of a collision?
Annoying as this can be, the driver with the right of way also has the right to change their mind about turning off the road at any particular point. In black and white terms you would've failed to give way. I'm always very wary at intersections because of this exact scenario.
Same as if some genius is indicating right when going straight thru a roundabout so if you pull out turning left, which would be fine if they acutally turned right but they hit you still your fault. Glaring oversight in traffic law that indicating and not following thru with it gets you off any resulting accident when people rely on the indication.
