Having been a scooter courier for a couple of years, there's a lot here that I recognise, although I never wanted to die quite as urgently as this chap does. Also, we had targets, this guy just likes going quickly.
There's a lot of quick-thinking skills on display here. However, there's also a lot of moves that are only possible because the bike is powerful, and spaces he can't get through because the bike is wide. In a race against a slim 110 CVT or step through, I honestly believe he would have lost.
It's high risk though. I did only 2 years as a courier, clocking 23,000 miles, 2000 drops and pretty much took a brand new scooter to it's grave through hard work. I crashed 3 or 4 times. One of them could have been particularly nasty (bike vs. bus) but I had enough presence of mind to launch myself into somebody's front garden through a privet hedge instead. I had to be pull out of hedge suspension by the bus driver, whilst the bike left a bike-shaped hole in the hedge and charged into somebody's front garden. The fact that I rode with a full-face helmet, almost always visor down, probably saved my sight in hindsight as well. Happy days!
