\team fortress 2\tf\cfg

put it in this folder, make a file called autoexec.cfg (and make sure it saves as a cfg file and not txt)
Steam\steamapps\common\Team Fortress 2\tf\custom\my_custom_stuff\cfg

That or you can go into the options in game and manually rebind your wasd to forward back left and right or just put this in your car instead of the script:
bind w +forward
bind s +back
bind a +moveleft
bind d +moveright

I have it, but I rarely utilize it. I just feel better knowing that if somehow my brain doesn't properly send a message to my fingers to let go of d and press a, it won't negatively effect me.
