It's funny that you mention Audi as your comparison because we had several (four) Audi's prior to these Tesla and every single one of them out-performed every single on of my AP1 Tesla Model S (six now) in every measurable way. When a few drips of moisture hit the windshield the Audi would trigger and clear it. My Tesla will wait until I can't see and usually by then I've already manually tapped the end to get them going because it's a dangerous situation. The AP1 Tesla also doesn't ramp up speed to match the amount of rain properly IMO. This part is a little nit picky and I could overlook it if the dang things just started at a proper point rather than waiting until you can't see the way they do. Lastly is the speed... it's awful. Maximum speed is about 50% on every other car I've owned and I've been in a couple of situations in parts of the country I've never been too where this created tremendously dangerous situations.
It's one thing to have your windshield covered along with the road covered with standing water on a road you've driven a hundred times (Although that's still super dangerous) but it's quite a different story to be somewhere you've never been before trying to navigate traffic, lanes and roads when you can't really see any of the above. I've had to pull over for safety due to rain which is something I've never had to do in any other car I've owned to include cars from the 80's & 90's with wiper tech what it was then. I get that that last part isn't so much of the automation piece so much as an example of how awful the wiper solution as a whole is with Tesla. If you could wave a magic want to get my early 2000's auto wipers from my 4.2L V8 A6 I'd pay good money to make that swap.
