I have a habit of always being the driver when playing OFP.. yet commander at the same time..

I get in as commander, get my crew in, switch to driver, then drive and still have tank commander control. It's mostly because the AI drivers haven't worked out the use of the "Fast" button or the theory that "Tank + Speed + Static object = Tank + speed - static object"

That, and I feel unsafe going anywhere without a rocket launcher, and only ever use single shot fire - while firing faster than automatic fire. Clickclickclickclick... xD
