Smart Fur and Points on cars

I drive home on a long two lane city avenue where cars are always stopping to turn either left or right and waiting for all the rush hour traffic coming the other way to break before they can make the turn and thus get out of the way. Until they do make the turn there is s long line of cars waiting behind them trying to get into the other lane. This stack of cars mostly peels off backwards so that the first car behind the turner is the last to get to change lanes.

Inefficient.

If cars had points then when a car in front of you decided to turn, your point, which would be pointed to the passing lane side of the car, would just slide you right around him on the passing side. It occurred to me that all this waiting is due to the inefficiently shaped square ends of cars.

On to the smart fur. Eventually software will do all of this blood cell type negotiation and flocking for us, but on the way there there will have to be a hardware side of it, so start making smart fur on cars now, in the form of antennae that will let you know when you get close to another car.
