Has anyone tried this DuPont Snow and Ice Repellant on their headlights? I just did some quick searching and found this. Seems like a possible solution for headlight buildup.

I looked through all the Q&A for this product on Amazon and saw conflicting recommendations for use on plastic. Since I have PPF on my headlights, I'm reluctant to use anything that could damage that plastic. Anyone have any experience with this on PPF?

We need tire companies to make winter tires for the 21 inch wheels. I doubt I'll get my R1S before late 2023 but living in CO already anxious about it.

Thanks for sharing your experience.

What setting do you have your regen set at? High or standard?
I was on Standard regen. It wasn't bad slipping, just noticeable. I don't think it'll be too hard to finesse with the throttle with a little more practice in the snow. Storm coming next week supposedly...

This has me a bit concerned. I live in a place where the roads are covered with ice throughout winter. Regen braking causing skidding could be dangerous. Having said that I have never driven an EV so not sure if this is something that will be easily/safely compensated for by driving technique. I look forward to more comments about winter driving...
@crashmtb is correct, you have to feather the throttle. It never felt like brakes locking up they way they would with an ICE vehicle and as soon as I pushed back on the throttle it corrected. It's just a new/different feeling that'll take some getting used to. I can see ultimately liking it more than how an ICE vehicle handles it since you're really not moving your foot back and forth between pedals. But I still think a low regen setting would be nice.

I haven't put this on my headlights but I use this on my snowblower and works great. I don't know off hand but I would check to make sure it's safe on plastic / acrylic surfaces. My snowblower is all metal so I don't worry about it..

My original plan was to stick with my 21ā€ wheels and OEM tires. But on Wednesday Bend had a bit of early morning sleet that coated my street with a thin layer of ice. My street has a steep slope to the main highway where it’s a T-intersection and I slid all the way down. Managed to avert an accident by aiming to the gravel shoulder. Ordered the 20ā€ AT’s that same morning. Anxious to test those on the next icy day.

As I have said on another thread I started about this very issue, my fear is hitting a patch of black ice on the highway (particularly I-87 in the mountains, especially in wind/snow) and having one of those heart-stopping moments where it is impossible not to lift your foot entirely by instinct. With the regen, I'm then sliding. With an ICE car on zero throttle I would be sliding/rolling. giving me a bit more time to correct.

Great thread and thanks to the OP for getting this started. I'm expecting to have issues here in Colorado as I'm running the 22" wheel/tire combo (had ordered the 20" combo but the Shop had a truck with everything on my config except the tires, so here we are). In the light snow we had yesterday in Colorado Springs, the roads were just wet but I did notice my headlights were completely covered - this was during the day, so minimal impact but night would be a different issue. I'll try some of the glass application products mentioned above but see this could be a significant problem. I don't expect any OTA improvements to address this...any other solutions/advice appreciated...
I doubt the 22's will be that bad to be honest, they are M+S rated and given the electric motors and weight of the vehicle I bet the Rivian handles just fine. I've driven my stock Model 3 in the snow the past few years with way less weight and regular tires and it's been fine. Bridgestone does make 22" Blizzak tires that would fit however if you really want the winter treads.

And they have absolutely tested in winter, see video below it was -20 in Minnesota!

Wouldn't virtually any car slide on a steep slope over a thin layer of ice regardless of tires? I still slide around sometimes on my Ford Explorer with Blizzak snow tires when there is ice out, they don't cure 100% of the slippage!

Absolutely, but with the softer rubber I’m counting on having just slightly more control on ice. Unfortunately, I was caught off guard (hadn’t had my coffee, yet) and I instinctively took my foot off the throttle instead of feathering it. I keep my regen set to standard but even a little less regen would have been helpful. I’m hoping Snow Mode comes soon.

DT...thanks for the response and the encouragement...I have seen those videos and it seems like it might be okay although impact of regen is still to be seen. I've considered the Blizzak but we don't usually have enough snow in the Springs to justify a dedicated snow tire...generally only about 10% of work days in winter months (another made up statistic by the way ;))...but seldom enough that I expect I would simply wear the tires out driving on dry roads most of the time. If conditions are too bad, I usually just stay home - and rarely (if ever) venture into the mountains when conditions are bad (my days of skiing are well behind me). Although hope is not a course of action, I'm hopeful that the 22" All Seasons will be adequate. Guess we'll see!

100% agree with snow mode, I turn my Tesla regen down when driving in snow and having this option with Rivian seems to be a no-brainer.

Honestly, sounds like you will be fine. And for what it's worth, I typically have my Blizzak's on my Explorer from Nov-Mar and I will get 2-3 seasons out of them before they need to be replaced so they wear quite well.
