Video: BMX ramp on a moving lorry

If James May's taught us one thing, it's that BMXers beat Fiat 500s through Hungarian traffic. But Red Bull's investigated the small bike/motorised vehicle dynamic further, and stuck a mini ramp on the back of a lorry.

A mini ramp that gets ridden by Venezuelan five-time X-Games Gold Medalist, Daniel Dhers. While the lorry's moving. In thick traffic. In Lima, Peru. Click play for much insanity. We're no experts on physics, but we're pretty sure this shouldn't really be possible.
