Our car has an automated system which provides an audio alert if there is judged to be too much rain for the journey to continue without stopping to put the hood up. When the noise gets too much for me, I do stop and put the roof up. The automated system then reverts to its normal role of providing over-speed / cornering-speed warning alerts.

When I am alone in the car, then these automated systems are disabled and I have to use my own judgement as to roof, speed and cornering-speed.

There was one occasion when the automated system lost her voice soon after we started a trip down the Fosse Way to see friends in Somerset. Journey time was substantially reduced on that occasion.
