Like the smart thermostat company that Google recently acquired, Dash helps users save money while being more environmentally friendly while they drive.
The idea is that you plug a dongle into your car's diagnostics board. That dongle, along with Dash's app, then tracks 300 data points about your driving, including how often you hard-break or speed. It uses that data to grade your driving.
Dash just hit a milestone - its users logged 5 million driving miles - and the startup used that data to discover some interesting statistics about where the best and worst drivers live.
