So this effort started because too many friends and colleagues have been hit from behind by texting-and-driving drivers.
These impacts, which would otherwise be a minor fender-bender between two cars, end up permanently reducing the quality of life of the biker. And higher speeds are fatal.
As a result, even seasoned bike commuters - in one of the safest places in the world to bike commute (Boulder) - have stopped doing so.
The goal, the 'why' of Commute Guardian, is to prevent these impacts.
