5. Space Captain/Super commander
What happens after we boldly go where no man (or woman) has gone before? With the launch of commercially available space-flights, popping up to the international space station or taking a cheeky jaunt to Jupiter could become commonplace. And, inevitably, there will be a massive recruitment effort to attract drivers.

One small step for man, one giant leap for commuters everywhere.
