Rule one. Always check the blades ain't stuck to the screen before
switching on. You can check this by lifting them off the screen against
the springs while scraping etc the ice off.

Rule two. Always check the automatic windscreen wiper setting is off
before turning on the ignition, or the sensor may interpret scraping the
windscreen or pouring tepid water on the windscreen/blades as "rain".

Do auto screen wiper cars not have sighted drivers?

Just ones that find it convenient.
