I don’t drive yet, but I found this really interesting. Basically the traffic lights try to detect traffic using electromagnetic coils which detect changes in conductivity from a car’s tires. Normally when a car pulls up, it will check if there are any other cars, and will adjust the lights accordingly. Unfortunately if you have a motorcycle or scooter, the sensor doesn’t always detect you. By taking a high-powered magnet and taping it to the underside of your motorcycle, sensors will detect you more easily, and you will hit less red lights. Of course, if you already have a big heavy car, this trick will not do much, because the sensors probably already detect your car. The best part is, this trick is completely legal!
