I'm no fan of Corbyn but I can't see that this is his fault.
If you look at the video, the car just does exactly what you would expect it to do. It drives forward towards the entrance it was obviously aiming for.
If you try to film a car close up, surely there is a risk of this happening? Obviously I wouldn't wish this on the poor cameraman, but I can't see how it is Corbyn's fault.
