while task.wait() do
if not script.Parent.Occupant then
script.Parent.MaxSpeed = 0
else script.Parent.MaxSpeed = 100
end
end
Server script, place inside the VehicleSeat instance of the vehicle.
local carSeat = script.Parent:WaitForChild("VehicleSeat")
carSeat:GetPropertyChangedSignal("Occupant"):Connect(function()
if carSeat.Occupant then --someone using car
carSeat.MaxSpeed = 100
elseif not carSeat.Occupant then --no one using car
carSeat.MaxSpeed = 0
end
end)
More efficient implementation of the same logic. You’ll need to place the 2nd script inside the vehicle model itself. Make sure the VehicleSeat instance is a direct child of that model so that the script can correctly reference it, like this:

Alright, so I put 2 scripts in the vehicle. CarOff1 is the first script you gave, and CarOff2 is the second script you gave. The VehicleSeat name of the car is “DriveSeat” so I changed the “VehicleSeat” to “DriveSeat” on the second script. Unfortunately, these scripts don’t seem to be working.
Here are the scripts below and where I have placed them:

Is that DriveSeat a VehicleSeat instance or just a regular Seat instance?

The DriveSeat is a VehicleSeat. The DriveSeat is what the driver sits in.

How is speed of the vehicle controlled normally?
All the speed is controlled through the A-Chassis Tune.
local carSeat = script.Parent:WaitForChild("VehicleSeat")
carSeat:GetPropertyChangedSignal("Occupant"):Connect(function()
if carSeat.Occupant then --someone using car
carSeat.MaxSpeed = 100
elseif not carSeat.Occupant then --no one using car
carSeat.MaxSpeed = 0
end
end)
Insert this script somewhere suitable within that script and control the speed however it is managed in that script. I think the MaxSpeed property only works for more primitive vehicles.
Yeah, it doesn’t work. No worries though, A-Chassis is so incredibly confusing it’s not even funny. I really appreciate the help! I’ll try and reach out to an A-Chassis dev and see if they have a solution.
I had the same problem, the way I fixed it was to anchor the wheels when the driving seat isn’t occupied
Howdy! It seems like you haven’t discovered my plugin that can totally get rid of that problem without having to anchor the vehicle!

To control an A-Chassis car, you change _GThrot and _GBrake in the Drive localscript.
They are controlled similarly to vehicleseat values, from -1 to 1.

Hi
if someone has a problem with the script and an error pops up, they probably have an older version of the chassis
<1.4 so if you want the script to work I recommend removing most of the script and adding
car.DriveSeat.ChildRemoved:connect(function(child)
if child.Name==“SeatWeld” and child:IsA(“Weld”) then
for i, v in pairs(car.Wheels:GetChildren()) do
v["#AV"].angularvelocity = Vector3.new(0,0,0)
v["#AV"].maxTorque = Vector3.new(2500,0,0)
end
end
end)

Is there a way to decrease the time until stopped? I know it depends on the initial speed, but is there a way to “divide” that time to make it shorter?

you can always change “v[”#AV"].maxTorque = Vector3.new(2500,0,0)" to like 3500 or higher

Hey, I just tested this and noticed that this is already in the script (I am using A-Chassis v6.52S2).
This code is at the end of Initialize script (Click to show)
--Driver Leave
car.DriveSeat.ChildRemoved:connect(function(child)
if child.Name=="SeatWeld" and child:IsA("Weld") then
--Remove Flip Force
if car.DriveSeat:FindFirstChild("Flip")~=nil then
car.DriveSeat.Flip.MaxTorque = Vector3.new()
end
--Remove Wheel Force
for i,v in pairs(car.Wheels:GetChildren()) do
if v:FindFirstChild("#AV")~=nil then
if v["#AV"]:IsA("BodyAngularVelocity") then
if v["#AV"].AngularVelocity.Magnitude>0 then
v["#AV"].AngularVelocity = Vector3.new(0,0,0)
v["#AV"].MaxTorque = Vector3.new(0,0,0)
end
else
warn('Maracujá')
if v["#AV"].AngularVelocity>0 then
v["#AV"].AngularVelocity = 0
v["#AV"].MotorMaxTorque = 0
end
end
end
end
end
end)
However, It doesn’t seems to work, the car just lose wheel force but continue foward until it stops after a long time going foward alone.
I already read some topics about this but still can’t solve this problem. Any help would be appreaciated.
Enabling parking brake when char leave vehicle seat: I’ve already tried activating the parking brake when the character leaves the DriveSeat, however this make the smoke effects on the wheels stay forever, as the drift plugin cannot remove them as the script is deleted when the player leaves the DriveSeat. So activating parking brake is not a solution also
Already tried MaxTorque = Vector3.new(X,0,0) with higher values for X but also unsucessful. 
Have you tried something like this?

Thank you for the reply. Just tested it and still has no effect on reducing the car speed. I also tried with exorbitant values like 99999 instead of 4000 but still makes no difference.
I welded on parts; one for each wheel, like brakes.
When the player exists I change those parts to CanCollide = true.
Works great.
try adding this for loop to the “drive” script when the player leaves Car
also when u leave a car look at workspace[car].wheel.#AV and see if force where apply
