The other cold weather questions I have are how the door handled and charge port doors going to function when the truck is covered in snow and ice. My Tesla does not always perform fantastically in those conditions.
Not great. Had to chip off ice around the frunk, gear tunnel, gear tunnel buttons (wish they and tailgate switch weren't on a horizontal surfaces), and charge port in order for them to function with most recent snow and ice storm. Unfortunately don't have garage space to park in. Door handles weren't directly impacted.

That’s pretty standard on any vehicle after a good freezing rain/ice storm. I’ve had to chip away the entire perimeter of doors and gas caps before. I had to chip the ice off the charge door actuator a few weeks ago in order for it to be able to close. Nothing unusual.

I can’t count the number of times I’ve needed to chip ice off my ICE truck, so fully expect to do the same here, with the added benefit that I can remote-heat the thing until most of it melts off anyway.

My daughter used to ask me why I carried a lighter around with me all the time when I don’t smoke. I had to explain that it was an old habit from living in the mountains and occasionally needing to melt a little ice off the lock cylinder of the Tundra.

ā€Melt the ice off your lock for a key?ā€ … ask your parents.

I'd say this is a luxury feature. If you live in a wet/slushy area on the ski slopes, you prop up the wipers when you park for the day or you defrost before driving. A few cars might have some luxury heated wiper thing, but otherwise we just deal with it.

I’ve seen what looks like wiper heating elements in the windshield but haven’t tested if they are functional. Maybe coming in a future software update?

No need, done that plenty of times myself. Also good for heating up the key itself so it will defrost the frozen tumblers inside the lock.

Oh no - ha, not you, sorry.

I was referring to the vast legions of people out there who have never seen an actual key to operate a car. My kids look at them with wonder and moderate derision, like it’s some medieval torture implement.

I will say that the combination out the gate of the OEM wiper blades (utter garbage) and the windshield defrost (often blows cold air) make a combo that renders the driver's side wiper dangerously useless (the ice build up on the left side of the windshield helps to freeze the wiper blade).

We made the trek home over Donner Summit on Friday during the 3 hour window that it was open, most of our driving in white out conditions. The driver's side wiper was so bad that I literally could not see out the windshield and spent most of the trip leaning to the passenger side to see. I continually turned on the defrost and it continually blew cold air. We finally figured out that we needed to leave the defrost off, set the heater to about 75 and only keep the dash vent turned on.

I've driven in these conditions many times, never had an issue with the iced blades like I did on the Rivian. Chatted with someone at the RAN charger who had the same problem as well.

The truck itself handled the snow and ice great and I never felt any loss of traction (20" OEM ATs), but the wiper situation leaves a bundle to be desired.

As for the other questions—we parked outside (didn't fit in the garage) and we managed to get all the doors open, but the frunk froze shut and there was no way to get it open. The slats of the tonneau cover are a wonderland for catching water that freezes, so we considered it frozen shut as well.

Just an icy, streaky mess.

I'm in upstate NY and well versed in these conditions. This winter has been abnormally mild but I typically combat this with copious amounts of deicer washer fluid and occasionally I will kick up the washer fluid a bit by adding an additional 1/2 bottle of 70% rubbing alcohol ( a whole bottle makes the fumes a bit harsh).
In general I agree that many EV's try to over automate the HVAC system. It would be better if we had the option to manually select the exact function of the heating element, A/C compressor, fan speed outside air damper, vent controls...

It's baffling to me that for 100 years, and over 10 years of EV's, No automobiles used heat pumps and then Tesla comes out with a heat pump system and people act like it's suddenly the only way to heat an automoble cabin.

It's pretty common to be driving in a good snowstorm and have the wiper blades freeze up with snow and Ice. It's happened on numerous cars I've owned and driven every winter in the Sierra's to Tahoe. If you don't have a heated windshield (heated pad where the wipers rest) you will get build-up on the wiper blades when the snow is flying. There's a simple cure when this situation happens:
  1. pull over,
  2. put the Wipers into "blade change position,
  3. get out of the car, lift the wiper blade off the window 2-3 inches then release to let them spring back on to the window. In many instances this will break up the ice off the blade
  4. Repeat 2-3 times to until the ice is removed from the blade. You may have to manually break it up. Repeat for the other blade.
I almost had to do this yesterday afternoon driving down from Echo Summit (7400') in my ICE car. I presume I'll have to do this in the Rivian when I [eventually] get it.

To carry off what @Trandall mentioned above, this is a time-tested method that's been in use for 100+ years.

I typically roll the driver window down and pull the wiper up off the windshield while still driving if traffic isn't heavy. Something on the Rivian wipers is a little sharp though, wouldn't recommend doing it this way.

Not really a hard problem to wrap one's head around. Nobody materially cared about the energy efficiency of an ICE vehicle's heating system in the context of widely available fueling stations and the capture of heat off of the engine. We started actually caring when EV range became a limiting factor while using a literal toaster oven to heat the cabin.

My "luxury" 2015 eGolf has a heated wiper bay. In fact, the way they designed the Hood overlap, you CAN'T prop up the wipers.
Thank you for your kind and inclusive explanation.

That's german engineering (and the location of the manufacturer of the car), but decidedly 90% of the stuff on the lot in the egolf price range does not have heated wipers. It's a very non-standard feature... although one that is at least becoming more popular.

You can prop the wipers on the Rivian (use service mode when parking), or remotely invoke the heat to melt them. The defrost and warmth mode will target that area. Other than that, having driven Tacomas/F150s/Ram pickups/Explorers/Durangos/and a fleet of rental cars in the Cascades and pacific northwest snow, we deal with it using defroster and propping wipers.

I'll be up front and say the Rivian doesn't strike me as the most snow-friendly vehicle, but it works fine.
