It's only taken about a million years, but someone has finally decided that improvements are possible in automobile braking lights. Students from Virginia Tech have developed a new system that can show not just whether you're stopping, but if you're slowing down, when you're about to stop, and how quickly you're pressing the pedal. The concept uses an array of horizontally arranged LED lights -- when you begin to slow, lights in the center glow orange, after a certain threshold side lights turn to red, and if you're slamming on the brake, they'll all flash red. The team, led by mechanical engineering Professor Mehdi Ahmadian, has plans for the system beyond the lab, though they speculate that it will be easier to add them as additional indicators on commercial vehicles at first. If this pans out, someday soon we may all be tailgating a totally psychedelic light show.

Looking to collect a little acceleration / braking data on the cheap? Even if you're just scouting alternative uses for that oh-so-handy Wiimote, a recent project from klee just may suit your fancy. A proud owner of a 2000 Volkswagen Jetta managed to rig up a Wiimote-based tracking system that gathered information on g-forces, acceleration, turning, and overall speed, and thanks to a little Excel computation, the results are neatly graphed once the outing concludes. Of course, you may need a little help in the script writing department, by judging by the looks of things, most everything you need is awaiting you in the read link -- you know, except your own Wiimote and a Vee-Dub.

Face detection on your average digicam may not seem that special, but strapping the feature atop your steering column can certainly make for a more enjoyable (and safer) driving experience. Lexus' new LS600hL sports a Driver Monitoring System, which places a detection device in front of the driver's seat that keeps a close eye on the orientation of the his / her face, and if it sees that you're peering off at the continually changing MINI billboard or checking out the overhead wind energy producer, it kicks into action. The system will send audible and visual alerts at first in an attempt to get your attention back, and can eventually "apply the brakes on its own" if the previous warnings prove futile. Moreover, it can reportedly "reprogram the steering ratio and amplify the intensity and quickness of the steering response" to keep motorists safe, but there's no word on whether or not a retinal scanner add-on will be available to automatically adjust user preferences depending on which driver hops in the seat.
