Why rich people like to be driven by chauffeurs? Do they ever go anywhere on foot or use public transports?

Never understood that. ... personally if i was rich i'd still go on foot and use public transports.

But i've noticed most rich people are always sit on the back seat of their luxury cars, being driven by chauffeurs. Are they FORCED to do it, or they like it actually?
