Not available where I live in Ohio.

Where I live in Florida, within my town it's just as easy to bike. To go to the next town (20 miles) would be a 2 hour bus trip with 2 transfers. I could tighten that up a little by biking some of the way, but there are no safe biking routes at most of my ultimate destinations in the next town.

When visiting Europe, DC or NYC we always use public transport. The latter two cities are frequent destinations (family nearby); other US cities, we're not so familiar with the public transportation network, also more likely to have a rental car, so somewhat less likely to use public transport.
