Why is my debounce not working even though I think I did it correctly?

So I did some tutorials here and there, and I'm trying to make the part blow up up every 55 seconds if it is touching the current part. But it won't even say that it's touching the model when I put it right on it.

local RESET_SECONDS = 1
local isTouched = false 
if not isTouched then  
	isTouched = true  
	script.Parent.Touched:Connect(function(obj)
		if obj:IsDescendantOf(game.workspace.car) then
			local explosion = Instance.new("Explosion")
			explosion.BlastRadius = 1000000
			
			
			explosion.Parent = game.Workspace
			explosion.Position = script.Parent.Position
			print('model touched')
			
		else
			print("couldn't find model")
		end
		
		wait(55)
	end)
	wait(RESET_SECONDS)  -- Wait for reset time duration
	isTouched = false  -- Reset variable to false
end
