Some car manufacturers have released technology which allows a car to see when you are getting too close to a car in front of you, adjusting your speed accordingly.

I imagine that using this technology along with local area networks you could improve on the existing technology to enable coordinated lanes. I think it could be incredibly interesting if you were able to have a lane on highways which only allowed linked cars to enter - they are each communicating to each other; establishing the speed of cars, as a group, instead of individually.

As I understand it, traffic delays frequently occur because of the ripple effect of one driver slowing down. If ther was a way to coordinate all cars accordingly, I presume that speeds could actually be increased significantly.

I read that Simulations show only 20% of cars need to have automated radar speed control to help make freeways free-flowing.

You just need to sprinkle smart cars liberally and everyone benefits.

from what we have seen, that's only if the house is making any money from the game. this is a friendly game and so should be safe under the law. see: http://www.pokerpages.com/articles/homepoker/augustine01.htm
