The intersection is one of the most difficult things because you’ve got two competing flows fighting for the same real estate,” Ratti explains. “So if you solve it, then the whole network would benefit.”... A future with digital, driverless vehicles sounds idyllic, but is it realistic? Well, part of that future is on the road right now. Jeff Manning owns a Tesla Model S... “It’s a stylish car, it can fit my family and a great deal of luggage,” he says. “It can fit me, I’m 6-foot-7, and I can’t fit in a Volt, I can’t fit in a Leaf, I can’t fit in the Toyota Prius, and that’s one of the reasons I got this car.”
Driverless will also have to deal with space utilization. Fact is that a Model S, Manning says he needs, occupies twice as much 'real estate' as say a Fiat 500.
