Disabling vehicle animations

Is there a way to disable the animation that occurs when a player enters a vehicle? I have a script that I use to adjust the player view, but when the animation activates it messes with the player’s eyeangles a short period after they get in the chair.

Basically, the script continually adjust the player eyeangles, but it seems once the vehicle animation is over (one or two seconds after entering), it snaps the player’s view to forward facing, which is pretty annoying.

I think you are looking for Vehicle:SetVehicleEntryAnim() but it wont be included till next update
