I agree with you there, go along to any testing station, and watch, they never deplete the air with engine stopped to see if audio buzzers or visual gauges work, time how long it takes to recharge, never use a jack or levers, never tap every visible nut with a small ball peen hammer, never get the driver to hold his foot on the brakes to check for leaks, never get the driver to wiggle the steering to check the ball joints, the time it has taken me to write this is longer than their 'test'. they should also have to book a time and date to arrive for testing, the whole system is pathetic, they don't have a clue on how to test correctly.
