Just remember that the Wheelman can do much more than just drive/pilot the vehicle. A well-designed wheelman does more than control the vehicle or just sit in the van. He also can be an infiltrator, an engineer, an outdoorsman (even an expert equestrian), or a trucker with a mean right hook and a talent for improvised weaponry.
I actually disgree with this statement. The Wheelman can do none of things by virtue of the wheelman class
that a character with the same skill options couldn't do.
Here's a challenge - instead of telling us you love the wheelman (noted), name me a character in popular espionage
fiction who is a monoclassed wheelman and nothing else.
I would say Bourne is not. Bond is not - each do things with cars, but neither is clearly, from the class ability style effects he demonstrates, a wheelman instead of being a soldier, troubleshooter, assassin, etc. They just happen to be very good in chases.
