News flash! Horse-buggy more time efficient than cars

We were driving through Amish country again.
Seeing their beautiful horses gliding along at 8 mph, it suddenly occurred to me, having just done another awful 3 hours of driving that day, that the horse-and-buggy is now more time efficient than cars. 

** The Amish only travel a maximum of 5-6 miles, about an hour, to get anywhere in their world.
** For car-drivers, a 2-3 hour trip is not unusual anymore.
How long can we go wasting 25% of our work day?
