Toyota's radar cruise-control

Somehow we don't like the idea of a way that enables people to be even lazier drivers, but Toyota says it's working on a radar-assisted cruise control system for cars. Designed for use during stop-and-go traffic jams, the system works by automatically tracking the speed of the car in front of you and sounding an alert whenever they stop.

PS - We've added a new category for "Transportation" just for covering stuff like amphibious cars, personal jetpacks, robotic speed boats, etc.
