You’re not unlucky, in the U.S. any charger that isn’t made by Tesla is unreliable. It’s been getting worse over time, and the only real hope is that every manufacturer is switching to Tesla’s charge port (now called NACS) and getting access to their Superchargers.
I had a non-Tesla EV and eventually got a Tesla because I need to road trip regularly and can’t handle chargers being down.
You can use the left scroll wheel on your steering wheel to adjust the wipers once you’ve pressed for a single wipe. Just click it right for more, left for less. No need to look at the screen at all really. There’s a little graphic on the wiper controls showing you this.
