Rideshare apps such as Uber have changed how many of us travel, as it's now easier than ever to book a private lift to your destination without relying on buses or trains.
But for many people, especially women, getting into a car with a stranger in control of where you go and which route you take can be unsettling - particularly if you're travelling alone.
That's why you'll often see people sharing their safety tips online to help others know what to do if they ever find themselves in a dangerous situation. One woman who shared her simple hack has been praised for doing so, after people said her idea was "terrifying and clever at the same time".
