I think it's the best of both worlds. If I could pack my family and my car onto a train in Florida and be in NY seven hours later, driving my own vehicle? That's perfect.
Seven hours? Are you talking about HSR or the current system we have?
I wanted to visit my brother in Va Beach from Tampa a few years ago. Having never been on a real train (as opposed to the Disneyland Train), I called Amtrak. The cost alone was prohibitive without adding the car and it was going to take something like 21 hours to go from Tampa to Richmond, Va and then I had to switch to a bus and that was going to take another 4 hours, if I am not mistaken.
Well, I drove instead which takes 14 hours... I know, I drove it yesterday.
