proudly state they turn off their auto start-stop every drive
They are old with reaction times that are measurable with an analogue stop watch, or their car has a poor implementation of the function that takes an age to start the car or their driving standards are so poor that they should be removed from the licensed drivers database.
My 84 year old dad and my 80 year old step-mother fall into the latter category (with the contra-indicated love of Europe to confuse things).
