If I’m to be the driver of your vehicle, and I’m capable of obtaining your vehicle, what use are you then? No one is indispensable, but everyone can value add. If you want to buy a car, learn to drive it yourself. Otherwise, just take a cab or other forms of public transport.
If you get what I mean, you get it, if you don’t, then forget it.
