This is my WAG: The nearest lane is oncoming (UK vs USA) so that is not the proper lane. The middlish lane appears to be too narrow to be a lane and my guess is it is some sort of squeeze lane for room if somebody is double parked (similar to the middle lane being a bidirectional pass lane). The lane the turning car is trying to get into and what looks to me to be the ONLY lane for his direction is the far lane.
But that is just a guess.
Further, I have no clue about the speed limits on that street, however the lambo does come from nowhere in the frame while the Mazda was halfway out. Knowing the supercars tend to have super brakes, the lambo *could* have at least attempted to decelerate... However, hearing the engine noises this was not the case, it appears the driver only tried to swerve and stayed on the gas until a split second before hitting the Mazda. Finally, brake lights did not come on until the lambo was LANDING and were not on when the rear of the car entered frame.
I am blaming the Lambo on this one. But I am betting if in the US the Mazda would take most blame.
