first of all, was the Lambo within speed limit? unlikely

i don't think it matters if he has right of way

I am sure Lambo is definitely not within speed limit. Nevertheless he has right of way. Supposedly.

he definitely has right of way, no argument. but you are already at fault by speeding

The lambo didn't give way

The vehicle was clearly already in his lane.

anyway, I meet pricks like this everyday on the road. Turn onto a lane in front of another car that was reasonably far away and they will squeeze you out to get back in front
