Skill or recklessness?
Or both...
WHILST there is undoubtedly some skill needed to pull off a wheelie, particularly one at a 90° angle. This video just screams stupidity. Pulling wheelies like that, at high-speed, in a built up area is just stupid. If you want to wheelie without endangering anyone else then okay, but when anyone, especially small unseen children could be between the cars, it's just reckless... Surely?
