TBH to me it look like he comes round the corner, tries to move to the left but is forced back by the car on the inside of him, as he moves back his rear end slips out so he blips the throttle to try n straighten it up and as he does that the other dude carries on walking into the wheelbase of his car n bang game over
Other thing to remember is that there is very little visibility in those cars unless its straight ahead or slightly to each side, imagine looking at 12`oclock on a clock as straight ahead, visibility to either side is only to where 9 o`clock and 3o`clock are, anything between 3 and 9 on the clock is invisible to them
