If it is your part of the project to cool the driver of the car, I would first look at a small electric pump to periodically inject a very fine water mist into the car. Evaporating water sucks huge amounts of heat out of the air and can be an effective people cooler. Your driver would be cooled by the cooler air produced and/or by some cool mist in the face.

If your goal is to keep the driver from suffering heat stroke in the summer Virginia heat, some frozen ice packs inside his clothes would also be good. There are "cool vests" available that use this technique to cool people working in hot environments, but you could make your own using a fishing vest.
You definitely want to cool just the driver--a small refrigeration unit that pumps cooled air directly into the driver's jumpsuit might be the way to go... and find a driver who understands that this isn't a luxury cruise. :-)
