Breathalyzers should be a more common feature on cars than they are. This new Geosat 6 from AvMap aims to make that a little more common with one being built right into the GPS. Now, granted, the driver has to be willing to take the test to see if they’re safe to drive…but one would hope that there are more people in the world that would be willing to do that than not.

This unit looks like it will be Europe only, but hopefully we’ll see more units like these state side as well in the near future.
