BMW has developed a Lane Departure Warning Sytem:

If your car starts drifting off the road, the steering wheel gives you force feedback. Very cool!!!

It's already offered on the 08 5 series.

This was my 3000th post. Cool

(I never look at post count, just randomly noticed)

Infiniti have been offering it on their cars for at least a couple of years.

Now you can safely snooze at the wheel :D.

Yea between Active Cruise and Lane Change Deviation warning it's like bmw is saying "here let us help you avoid a DUI."

I think that will now become a must for heavy drinkers.

"Yes, can I have the DUI package with the sport package?"
