Some day in the future, you’ll hail a cab, then a few minutes later, a driverless, autonomous vehicle will pull up to the curb.
You’ll hop into the back seat and off you go, leaving the driving to the computer.
Not so fast.
Driverless cars are indeed coming. Automakers are already road testing them in select US cities with standby drivers ready to take control of the steering wheel if anything goes haywire.
