One thing I've always wondered about is the dials or sliders for temperature settings in the car. Many of them (especially the linear sliders) seem to be set up in a logarithmic way rather than a direct linear scale. Although I'm not sure whether I'm basing that on the scale of the tick marks next to the slider or on my actual perception of the temperature -- probably the former...
