Yes, we implemented simple physical solutions such as wipers and window heaters in cars to maintain vision for drivers. What we didn't do was implement lidar to aid human drivers.
Simple physical solutions are available if necessary for the cameras too. I don't have a tesla so I don't know what measures they use to keep the cameras clean but I'm sure they've thought about it and designed for it.
Great-grandparent comment suggests that they did not, in fact, design for it. Assuming the best is nice when you have no information, but we have information.
I'm not assuming the best, I'm assuming basics. We've just watched a presentation where Tesla put immense resources and talent into designing a state of the art vision processing chip. Do you think they're going to let it be rendered useless by not implementing simple physical measures to keep vision coming in from the cameras? (What measures are already there plus easy opportunity for improvement). Of course not. Such a line of argumentation is transparently bogus. I don't know why the top level commenter's autopilot turned off in the snow but trying to argue that that shows that snow renders cameras useless and makes lidar necessary is stupid. Sorry for the strong language but really, I don't know how else to put it.
I have seen recent Teslas in person in the showrooms, and there doesn't appear to be any wiper for the cameras. Especially with a firsthand owner account just a few comments up I think it's actually only logical at this point to assume they didn't put wipers on the cameras.
Well they didn't do that either. They didn't do anything for it. But don't worry, FSD is just around the corner and the cars have all the hardware necessary, it's just a software problem now. And this time it's different than in 2016 when they said they had all the hardware they needed. And it's different from 2015 when they said the FSD was coming in 2016.
In our 2005 DARPA Grand Challenge vehicle, we had a system to clean the camera and LIDAR. It used a spray nozzle, and alternated spraying windshield cleaner and air. This is a commercial truck accessory used on mining trucks.
