I know of only 2 cars that are driven by 1 wheel:
- the T-Rex. It has a motorcycle type rear end, and the front looks like blunt F1 car without a spoiler. http://www.go-t-rex.com/
- go karts.
I think the problem being reffered to is torque steer. I think (could be wrong) that in front wheel drive cars the enginie powers the right front axle half which then transfers power to the left front. This, combined with less than perfect suspension and driveline setups allows for the right front to get more power than the left. When that happens, the car feels like its being driven by the right front. This doesn't happen in rear drive cars because everthing is symetrical.
