In Batman begins we saw how the pilot/driver of the tumbler can switch to a prone position for better control or the vehicle weapondry. http://www.deviantart.com/art/NEW-BATMOBILE-DESIGNS-19640136
Wouldn't this movement hurt Batman's legs? Would this position switch be possible at all?
Also, Batman asked Gordon "Can you drive stick" when requesting his help driving the batmobile. Even leaving this as a joke or catchy line, and supposing the tumbler can be driven as an automatic car, you still need to step on gas or brakes, which is unclear how can be done from that position.
So, is this shifting positions system possible (or just if we suspend disbelief?).
To clarify I'm asking if is really possible or reasonable switching to the prone position as seen in the movie without hurting the driver and then being able to control the vehicle.
