You might find yourself surprised at how many of these smaller cities are good to visit for no particular reason! Indianapolis does have more than just little ethnic restaurants in strip malls. Of course, you may run out of things to see and do there sooner than you would in NYC, but who really has time to travel that much, anyway? ;-)
You have a point about needing a car in any number of such smaller cities in America, but even in those places there is a central core that remains relatively walkable.

They're often pretty small though. I'm not familiar with Indianapolis specifically, but there's one smaller city I visit semi-regularly for work. It has a nice (relatively gentrified) downtown but it's, to be generous, maybe 15 x 10 blocks. And beyond that you mostly need a car. I'll have a day to kill there in a month or so and I'll probably end up renting a car for the day.
I also worked downtown of a similar city about a decade ago. Same thing. (And both old mill towns.)
