I think the current AI-driver is so good that is actually better than a responding human-driver

.
I have to say I like it very much this way. I can ride the turret, watching for enemies, easily go hull down or turret down ect. I can command my tank from commander's position just as efficiently like I had a good and responsive driver, without the need to find one. And you can have twice as much tanks on a map with that (if there is 20 players available, I prefer 20 tanks on map than 10 co-op tanks. After all, driving is not as fun as commanding and shooting. I would prefer to command a tank with a human gunner (or be the gunner in human-commanded tank), with AI-driver.
But IF I wanted to make an OPTION for being a little bit advantageous to have a human driver, I would:
- add a little bit of delay between pressing a left/right/front/right steering key, and the AI-driver reaction
- make the AI-driver a bit "chicken". In case the vehicle is damaged, AI-driver is abandoning it's station and "running away", leaving it empty. If the human-commander manages to survive, it would have to slowly switch driver/commander stations which is annoying - so human player "is better" because it won't leave you

.
Well, the whole computer-crew (with exeption of the loader, and maybe even him) could just run away from heavily damaged tank, leaving the human player alone. Human players tend to show little self-preservation and fight to the very end, where - on a real battlefield - tank would be usually abandoned by the surviving crew, after it got 1-2 penetrations.
- make the "steering" keys - left, right, front, rear - work as commands for the driver also when there IS a human driver. How am I supposed to tell him where to go, if the steering commands doesn't work ? I do not always use the vocal chat.
(well the steering keys were "dead" when I tried this once, a while ago, is this fixed? Someome was driving my tank, I pressed the steering keys with no apparent reaction, there was no spoken commands, don't know if he knew what keys I am pressing or not).
and - not connected - show somewhere on the screen who is in your the tank! (the nicks of the human players).
