Daft indicator switch
What must have been 10-15 years ago I test-drove a BMW 7-series. In every other modern car I have driven, the indicators are activated by moving the stalk up or down and, if you move it far enough, it stays there. The act of turning the steering wheel sufficiently far in the appropriate direction and then centring it returns the stalk to the off position. Not so on the BMW. The stalk would move a tiny amount then return to neutral. This would set the indicators going until the car’s electronics worked out that you’d made the turn.
This was fine for normal 90-degree turns at a junction; but once on a dual carriageway, having indicated to change lanes, I couldn’t turn it off again. Trying to move it back to neutral resulted in indicating the other way and so I would carry on, indicating left then right over and over until, for a reason unknown to this day, it would finally cancel.
After a while I felt it was easier to switch lanes without warning.
