There’s nothing like catching a good tailwind when you’re riding your bike. That’s why an engineer has developed a retractable sail you can mount on your bike to maximize the speed you gain from tailwinds. Of course, the sail isn’t intended for use on crowded city streets. That would just be crazy. The idea is more that touring cyclists could use it while cruising for long distances along country roads, potentially saving them a considerable amount of effort.
