The wiper will not clear the windshield it only smears and leaves streaks causing visibility issues. The automated wiping feature also ds not operate properly and it will wildly wipe at high speed with nothing on the window and then do nothing when it is covered in water and road dirt. It will also dry wipe for no reason and smear what ever is on the window causing a visibility issue and then with the unfortunate combination of poor washer fluid output and poor blade contact it cannot clean the windshield properly. To be clear, it ds not just take awhile to clean, it cannot clean the window regardless of how long you use the wiper wash function. It is a complete failure and I cannot get Tesla to address it. I made an appointment Dec. 6th for Jan. 31st (first available) and it was pushed, with no reason, to Feb 27th. After my current business trip, I will be discontinuing driving the vehicle if there is any chance of bad weather, it is that bad of an visibility issue and would be as unsafe as me driving without my glasses, looking through streaks and haze obscure important details I feel I cannot see the roadway good enough to operate the Cybertruck safely.
