Aaand that's why you want to make sure both brakes on your bike are fully working at all times.

You sail into an intersection on your bike, only to have a left-turner cross your path; you give your brakes a mighty squeeze and watch the distance between you close as the differential equation solver beneath your helmet flashes "no solution"; only a primal scream to get the driver's attention can save you from tumbling head-first over the hood now.

I'm glad to see that all parties involved escaped this incident relatively unscathed. But I'm less impressed by those Argentina supporters, who just carry along honkingly on their way.

Don't you just love how the World Cup brings people together?
