Not many opportunities for self employment in public transport.

There were none in the area in which I was working, but that didn't stop me
going off at a complete tangent and setting up my own business. That was
twenty years ago.

If you want a challenge, but are prepared to accept every (well almost
every) body as a friend, confidante then give it a go - the rewards are
generally far better than they ever would be working in public transport -
although I'd settle for the wages, pension and paid holidays of some train
drivers I know.
