Intro

Hello there! In physics, adding friction is multiplying the velocity by the coefficient, by doing so it decreases the velocity. However, when attempting to remove friction in certain directions, I ran across some strange behavior.

My attempt

I used a body velocity, and removed the body velocity's velocity by the right vector, then the left vector by lerping using friction

local BodyVelocity = workspace.Vehicle.BodyVelocity
function Physics:ApplyFriction(Friction)	
	--//Left and Right
	local RightVector = (Vehicle.PrimaryPart.CFrame * CFrame.Angles(0,math.rad(90),0)).LookVector
	local LeftVector = (Vehicle.PrimaryPart.CFrame * CFrame.Angles(0,math.rad(-90),0)).LookVector

	local RightFriction = BodyVelocity.Velocity * RightVector
	local LeftFriction = BodyVelocity.Velocity * LeftVector

	--//Right
	BodyVelocity.Velocity = BodyVelocity.Velocity:Lerp(BodyVelocity.Velocity - RightFriction, Friction)
	--//Left
	BodyVelocity.Velocity = BodyVelocity.Velocity:Lerp(BodyVelocity.Velocity - LeftFriction, Friction)
end

My problem

Firstly, this is very inefficient, secondly, It doesen't work that well, any suggestions to improve it?
