This post makes no sense at all, I mean no sense.
Do you drive your car with snow on the windshield... No... Do you drive without defrosting a foggy window or ice... No... You fix the problem so you can see.
Why is this different...........
I can clean my windshield while I am driving. I can not clean the cars camera and sensors while driving you - have to stop and get out to do this. E
And you seem to miss the whole point of the post. Elon/Tesla claims the model 3 has all the hardware needed to drive without anyone in the car. How can this work, when getting splashed by muddy water in the side of the car turns off auto pilot?
