There are two ways to get to work: by private transport or by public transport. Private transport usually takes the form of travelling by car; public transport, the bus or the train. Some, of course, choose different forms of cycling. If one can't afford a vehicle, one has little choice than to go by public transport. Those who can afford a car often buy one and drive themselves to work.
However, if one becomes very wealthy one may decide to hire a chauffeur so that one no longer has to drive oneself. Here I think that there is a sense of coming full-circle here. Doesn't a bus or train driver chauffeur those who travel by public transport? So, don't knock public transport; it's much the same, to my mind, as being chauffeur driven.
