I read the car was leaving the carpark, it's right near the corner, I suspect they've pulled out with nothing in sight and the guy has come around the corner way too fast and no time for them to get out of the way, the guy on the bike was going way too quick to correct also, his girlfriend was filming to capture him racing through the corner (so the story goes) the crowd of onlookers was perhaps incentive for him to be going as quick as he was, as he comes around the corner he's looking at the crowd and looks up when it's already too late
