Update: I forgot to embed the video earlier! It’s now here.
Act 1, Scene 1: A green bike lane busy with cyclists, including a pair of lycra-clad speed daemons on their spendy carbon fiber racing bikes.
Enter Fred dressed in normal clothes and riding his heavy cruiser bike much faster than those racer poseurs. Instead of slowing until it’s safe to pass (heaven forbid!), he tries to impress the pretty girl by veering to the right and jumping up onto the sidewalk.
Fred later posts at Bike Forums how he’s so much faster than the obviously unfit racers on their road bikes because he’s a lifestyle cyclist who rides everyday, while the poseurs just ride on the weekends.
The I Am Traffic website illustrates a number of these types of cycling that can significantly increase the danger of a crash when you’re riding a bike. It’s kind of TL;DR but you can find the full discussion here.
