NAME: Garnin Dash Cam 20
WHAT DOES IT DO: Everything you could ever need in any of these scenarios, with functionality to start and stop when you turn on your engine, a gravity sensor that knows when you've been in an accident, and built-in GPS to log the location of every bit of footage. It records in full HD onto an expandable microSD card, features a 2.3-inch display, and is pretty easy to install — so you'll always have video evidence of everything that happens on the road.
HOW MUCH: $250
FUN FACT: If they can figure out how to build this into a smartphone with GPS, then we'll be all set.
