why not raise teh speed limit to 100?
it would be cheeper and more used.
I don't know where you're from, but if the drivers I share the road with in the morning were allowed to drive 100mph I would most definitely be taking the train, no matter what the inconvenience.
I thought the democRats have been telling us that 55 saves fuel.
I remember back in the day before the 55mph laws that in certain parts of the country you could do 75-85 MPH. It sure made for a quick trip to Texas or Az driving through the deserts going that fast. If they build it make it go 300mph minimum. Hell I'd even drive there to ride a train going that fast just for gins and giggles.
