I have a small car, and it has a dual-tank: gas and LPG, which is a great way to reduce my car-related budget, as LPG is way cheaper. Unfortunately, when the tank is starting to get depleted, the car will emit strident and loud beeps to notify me about it. And every single time time, it startles me like Hell, which isn't something I appreciate very much, especially when I'm steering a 1 ton metal box to overtake a trailer at 130km/h on the highway. To make things even double-plus-good, a full-screen "LPG tank almost depleted!" message will cover the whole dashboard. The very same dashboard that constantly have at its bottom the current level of said LPG tank.
