This week I’m driving the 2018 Volkswagen Jetta SE – one trim up from the base model. It’s a no-frills sedan that doesn’t skimp on most modern “necessities” like power windows, keyless entry, and push-button start. There’s even a 6.3-inch touch screen with satellite radio, Apple CarPlay, and Android Auto. But one thing it’s missing is fancy controls for its HVAC system. Rather, this single-zone system has the three old-school knobs, three buttons, and nothing more. But you know what? It just works.
