Will we drive on underground automated highways?

Will we ever be able to take a subterranean road trip?­

We've already mentioned the possibility of driverless cars and even driverless taxicabs that will take you wherever you choose to go. While handing over controls of the vehicle may be an enticing offer for a lot of weary drivers, others may decide that they're not ready for this dramatic leap in technology. But we can't stop there. To take this thought one step further, we wondered what it would be like if the whole operation was under ground -- an Underground Automated Highway (UAH) system, to be exact.

Just imagine: A network of underground tunnels that stretches for hundreds if not thousands of miles. You'd drive to your local UAH tunnel entrance ramp, synch the vehicle's guidance system and let the automated highway system do the rest. At the end of your trip, you'd pilot your car the final few miles to your specific destination. Sounds simple, right? Well, its not. But it is a lot of fun to read about.

At least that's what we had in mind when we asked the question: Will we drive on underground automated highways?

But what if you're not really interested in public transportation? In fact, what if you're at the opposite end of the spectrum? Perhaps you're the type of person who wants to travel in style -- no matter what it costs. If that's you, then you'll definitely be interested in the question that comes in at number 2 on our list.
