My guess is that people impulse buy things that look sleek and shiny then suffer through the consequences

And many stupid decisions have no direct impact on the driver, but instead on those around the car. Like red beltline lights that don’t function as brake lights, instead using red lamps near the road that are easy to be obscured/ignored because the giant red lights above them look like brake lights.

Or dashes that are fully lit at night even if the headlights aren’t on, so the driver doesn’t have an obvious visual indicator that their tail lights aren’t lit.

So many rules I’d enforce were I king of the automakers.
