What happens when the truck driver guns it on a yellow and has 6 cars behind it? I'm guessing 2 or 3 T-bones and about 4 hours clearing up an intersection. For this system to work, all traffic lights will need to be reliably broadcasting their status and how long they're going to be remaining in it so that either the fleet can stop, or so that some of the cars can drop out to avoid running a red. It would also need to communicate with other vehicles. I can turn right (or left in some occasions here in Canada) on a red if I've got the room, but how do I tell if my fleet has the room? If the truck driver becomes liable for risking my vehicle then he's only ever going to move on his light and when he knows he has the time, which will only cripple intersections with congestion. It's a great idea and I can't wait for the day, but our road system is overly complex as it is and these systems will need to be equally as complex to guarantee safety. Edit: Also the driver of the fleet vehicles would need to know the destination and what exit the lead is taking. If I'm going to Montreal, I don't want to end up in downtown Toronto and spend forever trying to get back on the highway. Similarly, it will be especially dangerous if I'm just 'dropped' from the fleet due to a communication problem or if my vehicle doesn't follow because the lead is exiting before my destination is set to. IMO this system would do best as an advancement of an auto-driver system that can read lights and signals, etc. itself without endangering the driver.
