I have updated the mod required to make Alternative Vehicle Control possible, which can then be used with custom keybinds for which a few examples follow below.
Arrow Key Vehicle Controls ↑↓←→
Note:
Requires the ‘Alt-Vehicle’ mod, listed below. Without the mod, movement would be completely locked to the mouse!
Put the 4 Buttons (Up, Down, Left, Right) first, then their respective ‘MouseUnbound’ counterparts last, in the same order, to have a total of 8 blocks for 4 binds.

Note:
Requires the ‘Alt-Vehicle’ + ‘KeyP-Disabled’ mods, listed below. Without the mods, movement would be completely locked to the mouse and the P key would have binding conflicts!
Put the 4 Buttons (KeyP, Semicolon, KeyL, Hash) first, then their respective ‘MouseUnbound’ counterparts last, in the same order, to have a total of 8 blocks for 4 binds.

Alt-Vehicle 
This mod re-enables the alternative vehicle control again, so it can be controlled with keyboard input without the use of a mouse. The mouse only allows you to look around.
Alters the file GCVEHICLEGLOBALS.MBIN
KeyP-Disabled
This mod disables the fixed P key functionality, used for some of the main menu options in various in-game situations. The game now only uses the Escape key alternative, allowing the P key to be freely re-assigned. This allows for better customisation, especially for those preferring the use of PL;'.
Alters the file GCINPUTBINDINGS_WIN_KEYBOARD.MBIN
Alt-Vehicle + KeyP-Disabled
A combination of both the above.
Alters the files GCVEHICLEGLOBALS.MBIN and GCINPUTBINDINGS_WIN_KEYBOARD.MBIN
Installation
Look for the location your game files are installed, then make sure to create a MODS (case sensitive) folder inside PCBANKS if not present already.
Note: Do NOT use the imposter MODS folder already present alongside PCBANKS.
Remove or rename the DISABLEMODS.txt inside PCBANKS. This will now show a warning for using mods, when launching the game.
Warning
Using mods, is at your own risk! When the game releases an update, it is likely for mods to break. I can not be held responsible; you are free to question me
