sounds like fun BUT....
1. typing/loking at a computer screen while driving is extremely un-safe and illegal in many areas.
2. the wireless lan stuff is located in a ham band. boosting the power, connecting external antennas, or any other modifications to the equipment is illegal and causes interferance problems to the primary users.
If you are still reading...hams are now starting to use the wireless lan stuff to maintain computer network conections for public service agencies in emergency situations. attempting to send stuff over existing ham data systems is very s l o w and presents 'content' issues. wireless lan gets around some of the problems.
