10 Usual Tricks For The Car, Not Work

The car world also has its good handful of infallible tricks that are passed down from parents to children and from older siblings to minors as if they were the secret of the Holy Grail. And in case that wasn’t enough, the Internet has further multiplied the phenomenon. They are absolutely useless and were actually already known…, but everyone likes to believe that they will work.

10. Cheating on radar

It’s older than the rabbit trick in the joker and like this, a classic… Only a lot less lucid. It’s about varnishing the license plate with the idea that the shiny varnish will reflect the flashlight and make the car more invisible than a stealth fighter. The same principle – that of the flash of plucking to radar – look for variations on the same subject: shiny adhesives, CDs, and the like. The current devices are immune to these stumbles, so it’s not worth spending the money on varnish…

9. The human amplifier

It has recently gone viral and despite this, and in spite of the absurdity, it has become one of the best. It basically consists of supporting the remote control opening the doors on the chin and opening the mouth in the direction of the car to supposedly double the range of the operation of the controller. The idea is that the skull acts as a soundboard and amplifies the signal. But it doesn’t work…


Without a doubt, the most feared circumstance and the one that carries the most tricks is still to blow the dreaded breathalyzer. The list of home remedies that “a friend of our cousin saved from a good one” is as extensive as it is grotesque; from sucking coffee beans to eating garlic or licking batteries, swallowing toothpaste, and even chewing grass. It certainly sounds ridiculous… but still almost 11% of drivers admit to having once tried to trick the damn device with one of these tricks. And 100% of these motorists surveyed also acknowledge that they didn’t work.

7. Manual cooling

It may happen that the car has stayed in the sun and on the return, its interior is uninhabitable by the heat. Pragmatics assume that because technology is to make things easier, the car has a fantastic air conditioner with which it is enough to give it a little button and in a few seconds… voila! But there are hard-working cooling craftsmen who ensure that lowering a window and opening and closing the door on the other side has the same effect. Truckers have been doing it for decades and effectively creates a stream of air that can help… to connect our air conditioner with less burden.

6. Very dead point

Another reference that even showed up in the schools in the 1960s is to lower a stalemate to save fuel. In terms of consumption, it may have had some reason to be when cars were carrying huge double-bodied carburetors, but right now it’s nonsense and anachronism; The current CDI power supply system optimizes fuel flow to engine speed, so it’s absolutely useless to turn the vehicle into a downhill scooter. Well… something is saved: it saves traction because it overrides one of the three force vectors that ensure grip to the pavement of our car, so nonsense can end up in a mess.

5. Morning fuel

Another tip a thousand times repeated is that filling the tank in the morning helps to save because with heat the gases expand so that if the outside temperature is low it fits more fuel in the tank. Admittedly, it is true – that is why racing cars cool their fuel – but in a streetcar the difference is invaluable. In front, because the dilation factor of gasoline is very poor; for each degree Celsius that raises the temperature, the volume of gasoline will increase by 1-1000. And especially because gas station tanks are placed underground precisely to keep them at a constant temperature.

4. The pressure to remove and put

There is such a strange insistence on lowering tire pressure for any reason; in winter too, supposedly – gain contact surface and in summer thinking that the air inside will expand and overinflate them. Well… surprise! It turns out that tire factory engineers have already thought about it. The only thing to alter the pressure of the rubbers is to deform them and increase wear more through the edge area.

3. A dirty new car

A father’s advice, formerly (with the best will) was that he should not wash the car until after some time. Doing so is supposed to reinforce the hardness of the varnish that covers the paint. It is an idea born of the early years of the automotive when the lacquer with which the body was protected was more rudimentary and took months to acquire the desirable hardness. Indeed, in some cases, excessive contact with water could soften it in such a way that small impacts were marked. Today the painting and hardening processes are light years away and allow you to take the car directly to the washing tunnel as soon as you leave the dealership without the slightest problem.

2. The Criminal Accelerator

Probably one of the most widespread and also one of the most harmful despite seeming harmless. The accelerator before the engine shuts down is born from a custom of the old diesel engines in which it was done just before the strangler closed the gas oil pass to leave the circuit priming. In carburetor-powered gasoline engines, the engine-turning engine would leave the fuel-soaked cylinders and intake manifold unburned that enriched the mixture when it was touching to start cold.

But not only does the accelerator not make any sense in injection engines but leaving the fuel mixture unburned significantly shortens the life of the catalyst. And in turbo engines, the only thing that is achieved by accelerating the turbine before shutting down the thruster is to leave it without pressure lubrication and damage it.

1. The opening ‘my balls’.

It is becoming less frequent to leave the keys inside the car because manufacturers have already implemented a multitude of systems to avoid it, and in fact, many cars no longer have a lock. But for a while, the hoax ran – as an emergency solution for this problem – that pressing a tennis ball with a hole directly into the lock put enough pressure on the air it contained to move the gears and the door to open.

The supposed infallible remedy became so popular that even myth hunters dedicated one of their programs to it. Unfortunately, he was late; by then thousands of wretched tennis balls sacrificed for the sake of a completely absurd trick had been pierced.
