The way they do it with "Chunnel" trains is another way. Cars are loaded on trains and the drivers ride in adjacent passenger cars.

I thought the same thing (Chunnel concept), except that for the Indy-Chicago trip, somehow the load/unload time will have to be quick enough to justify the time.

Of course it will take a lot more energy to transport a car+passengers than it would to just transport the passengers without the car. In which case the cost of a ticket may be high.
