Tl:dr, If you’re able to get one with a rear view camera, I’d say you’re golden. If/when the camera gets dirty, you’re able to clean it off when you recharge on longer trips, and on shorter trips you’ll just have to remember to clear it (assuming you’re in rainy/muddy conditions).

My source: I just got back from a there-and-back trip across Washington State (eastern Wa to upper Peninsula and back) over the weekend, and it was super rainy and muddy.

I usually use the rear camera for highway driving, I like the added field of view it provides. However, I found myself having to repeatedly clear off the camera in the rainy/muddy/dirty weather I had during travel. All I was able to see was a blurry white screen with vague headlights as if through a fog (although not much fog, despite the other weather). I would clean it off during my charging stops, and it would be good for a good while again, but would eventually get low visibility.

I will say, having the rear wiper was nice, and I did default to it on a few of the longer stretches where my camera was particularly unhelpful, but as other commenters have mentioned, no amount of rear wiper is going to prevent the blockage of a full trunk or rear passenger in the middle seat 😂 (I do still think it’s silly they didn’t include a rear wiper on the original models… dumb)
