My old AA van had a warning light in the centre of the cluster, which was distractingly bright, to tell me my lights were on. I knew they were on, I didn't need blinding! The worst part was that when I removed the bulb, the workshop would replace it at service time.
In my current car I use a few single-track roads with passing places, which are basically little more than a bit of grass verge. When I pull away, occasionally I get a bit of slippage on a tyre, especially after rain. I instantly get an idiot light telling me that my traction control is switched off and would I like to turn it on. I know the wheel slipped, I both heard it and felt it, and no, I don't want the traction control on or I would have turned it on myself!
Someone I once worked with used to say that she considered the Patrols as her little treasures, who should be buried on a desert island far away. I often feel that way about car designers.
