When I first got my S, if you left the windshield wipers on the automatic setting, and it had rained in the recent past, when you unlocked the car and opened the door, the wipers would activate once and throw water on you.

Mercedes, which uses the same wiper system, had the same bug.

The difference is that Mercedes never fixed those cars. Tesla did.

So yes, there are issues. But it's not a straight win for either Tesla or non-Tesla. It's just different.
