The Chattanooga Police have new Technology that shows how many inches a car is from a bicyclist when passing from behind.  They are using the new tool to educate drivers about the three Foot Law.

This is great and I would love to see this spread.  Passing a cyclist at less than three feet is extremely dangerous.  Wisconsin has had a three foot law for many years.  Unfortunately, many people are unaware of it including some police and sheriffs.  Tell all your friends!
