I think most of it comes down to the driver's capability. You can find out how comfortable he is, and you can have a 2nd joystick to power the steering motor, or you can use the x-axis... but if you do that, it can become a mess, cause naturally you angle sometimes when going forward, and if u angle it a bit, the wheels will keep turning... not good. I know Krunch had a flip switch they did on the joystick, in 1 mode the wheels would turn the same and it would maneuver left and right, but couldnt turn, the other would have it where when the front wheels turned left, the back would turn right, so the robot would spin and act like a normal bot, you could program this by using the inverse number (so instead of I.e. 255 [which would be too fast more than likely] it would inverse and use 0 if you used a math equation) and the wheels would turn opposite so u could turn. All depends in how the steering is setup, but I imagine it could be easy to code, then you can adjust numbers to make it not spin so fast, or spin faster, and then the driver just has to learn it and get a feel for it.
