Attempting to Make HingeConstraint Car Tank Steering

Just making a car that uses motors and servos to drive be able to steer with A and D alone.

If someone would like to provide a helpful guide feel free to do so.

I’m hoping I don’t need to provide too much context pertaining to the code.

-- get the specifications
local speed 		= script.speed.Value
local accleration 	= script.acceleration.Value
local steeringspeed = script.steeringSpeed.Value
local steeringangle = script.steeringAngle.Value

-- set up the shortcuts
local vehicle	= script.Parent.Parent
local seat 		= script.Parent

-- find the tires
local A			= vehicle.A		-- front left
local AA		= vehicle.AA	-- front right
local B			= vehicle.B		-- back left
local BB		= vehicle.BB	-- back right

-- find the steering mechanism
local steerA	= vehicle.SteeringA.Servo
local steerB	= vehicle.SteeringB.Servo


-- set up wheels' motor accerlation
A.Motor.MotorMaxTorque 		= accleration
AA.Motor.MotorMaxTorque 	= accleration
B.Motor.MotorMaxTorque 		= accleration
BB.Motor.MotorMaxTorque 	= accleration

while true do

	-- power the wheels
	local velocity = seat.Throttle * speed -- use the seat's throttle to determine the wheels' action (backward? forward? nothing?)
	local steer = seat.Steer

	if steer == '1' then
		A.Motor.AngularVelocity 	= -velocity
		AA.Motor.AngularVelocity 	= -velocity
		B.Motor.AngularVelocity 	= -velocity
		BB.Motor.AngularVelocity	= -velocity
			
	elseif steer == '-1' then
		A.Motor.AngularVelocity 	= velocity
		AA.Motor.AngularVelocity 	= velocity
		B.Motor.AngularVelocity 	= velocity
		BB.Motor.AngularVelocity	= velocity
			
	else
		A.Motor.AngularVelocity 	= velocity
		AA.Motor.AngularVelocity 	= velocity
		B.Motor.AngularVelocity 	= -velocity
		BB.Motor.AngularVelocity	= -velocity
		end
	wait()

	-- steering
	local steering = seat.Throttle * speed
	steerA.AngularSpeed = steeringspeed
		steerA.ServoMaxTorque = 100000000
		steerA.TargetAngle = steeringangle*seat.Steer
	steerB.AngularSpeed = steeringspeed
		steerB.ServoMaxTorque = 100000000
		steerB.TargetAngle = steeringangle*seat.Steer
end

I have already made this much of an attempt and I’m ready to call it a night.

I need to make this clear: My intention with this post is to find a solution to modify this code to allow for the wheels to tank-steer using A and D. It currently does not perform this action.
