How Does This Happen?!?

A man, possibly quite old i would say, has managed to do this at a garage forecourt. Quite spectacular really, i suppose. But how did he do it?

Here's the link.

Before I click the linky I bet ya he pressed the accelerator instead of the break!

Just looked and no explanation but I bet thats what happened. Either that or the old fella was concentrating on getting a Worther's Origional out the glove box
