Driver is a designation continuing for a long time. Driver means one who drives. The man/woman who drives a plane is called Pilot. A pilot mean one who pilots. Fully correct. Now the driving of the train, car, bus etc. also have been much technically upgraded from the old driving. There is full justification to change that designation also.

I think this will suit: Airlines/ Flight Pilot, Train Pilot, Car Pilot. Why not all the drivers be called pilots? It will feel nice.
