I've been riding far too many 15's, 29's and 68's to know that bus driver was giving Bolt a chance to show off. I've been in many colectivos that would have given him a run for this money (no pun intended).
That said, I met Bolt at a Puma event in Boston, and the guy just seems to enjoy hanging around his fans. Sure, he gets paid a ton to do this, so I'd have a huge smile as well if I got one-tenth of his paycheck. But still, with so many diva athletes out there who won't even sign an autograph for the fans that spend their hard-earned money to finance their lavish lifestyle, it's refreshing to see a guy with this attitude.
