We would need to go out there with radios at about 0500, make sure no one is out there who would freak out to look in the mirror and see some invisible bicycle rider coming up on her ass. Then we see how fast that bicycle would get going before catastrophic spectacular epic fail. Ideally we could station proles right at the most likely hairpin failure sites to record the destruction. Post to YouTube, get lotsa followers, sell ads, make a buttload. More importantly, other amateur controls engineers would see it and want to play too.
