Tennessee is one of 24 states that have adopted a law requiring vehicles to stay 3 feet from cyclists, but there's really no way to effectively enforce it.

Chattanooga hopes to secure $36 million to install 330 miles of bike facilities over the next four years. To make roads safer for cyclists and motorists, the city's launched a Safe Biking Initiative (SBI) and is supposedly the first to adopt technology that detects, captures, and displays the proximity of passing vehicles.

Developed by Codaxus LLC of Austin, Texas, the Bicyclist and Safe Monitoring Applied Radar Technology (BSMART) is designed for municipalities which have or are considering bicycle passing laws. The ultrasonic sensor attaches to the handlebars and alerts the cyclist via sound and LED when a passing vehicle triggers a preset distance threshold.

Kinda cool.
