Why Your Car Thermometer Is So Bad at Telling the Temperature
Summary: Sometimes outside car thermometers are so inaccurate that they feel like random number generators. They’re basically the worst feature of the car, next to the car’s infotainment systems. That’s because they’re not actually thermometers, they’re actually thermistors. What’s the difference? Unlike a thermometer, which measures heat, a thermistor measures the changes in electrical current after heat is added or removed.
