How do I set a speed limit on a-chassis?

So, I've been looking through the internet for solutions to this, but just can't find it.

I've tried this solution and this solution, but they didn't work. So, I made an abomination of a script (normal script) which is here:

local car = script.Parent
local velocity = car:WaitForChild("Values"):WaitForChild("Velocity")
car:WaitForChild("Values"):WaitForChild("Velocity").Changed:Connect(function()
	if (velocity > 59) then
		velocity = 59
	end
end)

I'm pretty sure I'm half way there, but something's missing.

If you could help me out it would be massively appreciated!

First off, velocity will never change since it is pre defined, second, you need to reference the VALUE property of the velocity. (Assuming velocity is a intvalue or numbervalue)

local car = script.Parent
car:WaitForChild("Values"):WaitForChild("Velocity").Changed:Connect(function()
	local velocity = car:WaitForChild("Values"):WaitForChild("Velocity")
	if (velocity.Value >= 59) then
		velocity.Value = 59
	end
end)
