Comment: And end to traffic/congestion? Doubtful... (Score 1) 648
'Congestion would be something you could tell your grandchildren about, once upon a time.'
I find that claim highly suspect. Just because a car can self-drive doesn't mean the highways wouldn't be congested. In fact I'd argue that the exact opposite is true.
I live outside of Boston where we had to deal with the Big Dig for roughly a full decade. For those of you unfamiliar with it, this was essentially a project to replace the central elevated highway through the city with a larger underground tunnel (along with other new highway improvements). Before the start of the Big Dig the highway through Boston was designed to handle an estimated 90,000 cars per day, but that capacity was exceeded just one year after the highway had been built in 1960, and traffic jams were commonplace.
Since the completion of the Big Dig there have been studies that suggest the increased capacity of the highway hasn't resulted in less traffic. Instead, more people are now driving (and driving by themselves instead of carpooling) because they see the highways as better able to handle the capacity. If anything the traffic jams are bigger and extending further out from the city.
Driverless cars are likely to invite more people to hop into cars (and likely be alone rather than carpooling), so there will likely be many more cars on the road thanks to this technology. How does having a much larger number of cars, even when some or even most of them are automated, reduce or eliminate traffic/congestion if a road is only designed to handle so many cars per hour/day?
