Wifi Highway - could this work?

The falling asleep thing has pretty much been solved in a nice low-tech 
way in most of the states I drive in, some subset of: VA, MD, WV, PA, 
and OH.  They just grind wide grooves perpendicular to the road just 
past the border lines.  When you stray into them, you get a sound and 
vibration alert that you are heading off the road.  Elegant and caught 
on in about 2 years.  Of course it's not foolproof but it helps.

I just suffered through a couple thousand miles of sleepy driving during 
the holidays.  It is definitely the most likely way for me to die 
accidentally, even with my street skating in DC ( http://www.skatedc.org 
) or my flying, hiking, etc. http://sdw.st .

On the other hand, I'm getting my private pilots license to avoid all 
that driving.  No chance of falling asleep flying...
