What was the worst feature of a car that you've come across?

I always assumed that the ten inch doughnut spare wheel that came with my first car was a bad idea. Until I came across the video screen gauge cluster in a rental car I had in Taiwan about five years ago. It was a Dahiatsu Copen, a diminutive Japanese convertible, whose gauges at every stop would turn from indicators of speed, fuel and revs to a chintzy sunset with cotton candy clouds that would've made the ones from 'The Simpsons' intro seem complex. Simply lame.
