Unfortunately this will require a lot more than technology. It will require forward-thinking public policy that just doesn't exist at any level of government. Frankly, it's not in the interest of lawmakers and bureaucrats to consider the breakthrough possibilities. Instead, we're stuck with subways that will cost a fortune, take forever to build, and not improve traffic congestion one iota. Sigh.
*From Adam Ozimek:
Skeptics cite our deep aversion to handing over control to a computer as an impediment to the driverless car. But it need not be the case that the first time you hand control to a robot it will have you barreling down the interstate at 70 miles-per-hour. Autonomous driving might first be used for slow moving, stop-and-go traffic. You can see a precursor to this in cars that are already parking themselves. We can ease our way into comfort with it. We should have little doubt: driverless cars are in our future.
