Why do cars go up to 160?

Cars often have speedometers that go up to 160 mph to signal that they are capable of high performance, even if most drivers will never reach those speeds. Automakers use this as a marketing tool to appeal to buyers by implying power and speed. However, having such a high number on the dial can tempt some drivers—especially younger or less experienced ones—to test the vehicle’s limits, which can be dangerous.
