Riding a scooter isn't as easy as you think. Looking at it, it seems all you need to do is sit on the thing and twist one of the handles.
In reality, they're tempestuous beasties, difficult to steer and even harder to brake. Balancing the buggers is like standing on an egg sometimes.
For visual proof of the unreliability of these two-wheeled terrors, take a look at this YouTube video of an unknown scooterer attempting some scootering in a car park when everything suddenly goes really rather wrong.
Of course, it's not the first time a scooter has been involved in an epic fail online - here's a priceless clip of two bank robbers attempting to get away on a scooter that won't go faster than about walking pace. Happy days!
