Once he gets out of Downtown, Hiro twists his throttle up to the max and covers the remaining thirty-two thousand and some kilometers in the space of about ten minutes. Over his head, the express trains are whooshing down the track at a metaphorical speed of ten thousand miles per hour; he passes them like they're standing still. This only works because he's riding in an absolutely straight line. He's got a routine coded into his motorcycle software that makes it follow the monorail track automatically so that he doesn't even have to worry about steering it.
