If you are a typical American you are likely to be interacting exclusively with the upper class. Even if they don't feel upper class to you, by local standards they are at worst upper middle class.

I'm from a middle class family in Delhi, and we never had (or could have) afforded a driver full time. Maybe now, my father can, but it is still expensive and not worth it. Most middle class families don't have a driver IMO. Much more common with upper middle class. However, we did hire driver for couple of days in rural areas every now and then.
