hadhart,
You say: '..fde for something that doesn't fly'. Well it's top speed is 170 Mph, so that's almost flying. The video of Pinto 'flying' was the 'Before' (aircraft.cfg) tweak. The 'After' shows it jamming but not flying (crashing). Max Speed can be tuned to be 170 Mph (145 kts) if you want. I got the FDE (mostly) from Hama's BMW cfg and air, and added my 'touch/mods' specifically for vehicles to both.
If you want to drive vehicles FAST in Sims you will need some 'finger tip' control of controls. 1st is throttle. A joy slider is ackward to use. I use a 10 key pad (USB) with keys maped to throttle (F1,F2,F3,F4), spoiler, view change (top down), parking brake, etc, and sits to left of regular keypad, with right hand will be on joystick for steering (twist grip) and brakes. The spoiler as it's used for braking before going into turn and removed to continue after making turn so I can toggle without look at keyboard. And it happens fast, so no time to 'look' anywhere on curves. Without spoiler you can't make turns as brakes will never be strong enough to slow you down to avoid a crash.
So your 'attitude', or 'outlook', will have to be modified for vehicle driving (my FDEs anyway). Other FDEs allow you to drive 40 kts and that is it and on turn will let you flip and spin endlessly in air. I never have found any OTHER FDEs that work 'seamlessly' with vehicles. Let me know.
