They are called 'driver aids', my car has many of them, and I am quite grateful for them. They allow me to maintain more of my attention on the road itself. I don't have to keep turning the wipers on and off, or adjusting their speed - it rains, the wipers just run, and keep the screen clear. Back in the day, driving, I had plenty of spare time to switch them on and off, but the roads are very much busier now, than then, and driving standards are much worse, in part due to other's impatience, and in car distractions.
