Note that a 26% grade is "only" 15 degrees. For on-road use it might be useful to optionally display the angle in percent rather than degrees.

FYI, I did a little experimentation with the pitch and roll indicators. It seems that the little red lines for pitch are at 45 degrees while the ones for roll are at 35 degrees: (No, I didn't do both of those at the same time! This was pasted up with Photoshop from two separate trials.) IMHO...

Yes! Those of us with eyes that have seen a few too many decades can have a hard time with Rivian's teeny font sizes.

My take: this is a major step forward with a bit of room for improvement. * taking away the trip meters in Off-Road mode is a bummer; I frequently use off-road guide books that have all the turns and points of interest referenced by mileage from the start. There's plenty of room for nine...

A Rivian mobile service tech fixed my stuck powered tonneau cover today. The fix: lots of water! After messing a round a little with his computer he asked for a hose and sprayed a ton of water all over the thing. Et voila! Now it works ”as new”. But just to be safe, I’m leaving it open until the...

I'm sure it would be easy enough with the All Season tires. The biggest risk is getting a flat by hitting a rock with the side wall. And that's not much different with the AT tires.

thanks. That backs up my intuition that to make it up Hell's Gate I had to not stop.

Well, mostly. But sometimes lateral movement is helpful. You'll find lots of videos of Jeeps spinning all 4 for a few seconds with some lateral movement until just the right spot is found and traction resumes. Done carefully this is a useful technique. So let the accelerator pedal be the...

Well, that depends on how fast the reaction is. Maybe Rivian needs a faster computer?

Is that what it means when it says "Performance limited"?? I've had that a couple of times and always assumed it was some sort of traction control nanny-ism. "Oh, no! your wheels are spinning! I'm going to shut you down." But if it really is overheating, then the warning message should say so.

Very nice. I don't think I could have done it that slowly with the R1T.

I'm envisioning a different way to thinking about the accelerator pedal. Usually we think of it as controlling the amount of force applied to the wheels. Perhaps in very low speed rock crawling situations it should instead by a simple speed control: push down, the wheels spin faster; each...

Wouldn't it be cheaper and easier to beef up the cooling system?

Yes! But I think I would put the upper limit at more like 5 or 6mph. The trick would be to, via software, transfer the torque previously applied to a slipping wheel to the others that still have traction. That's what a mechanical locker does. What matters is to maintain a constant amount of...

I was running about 24 psi in all 4 tires.

I'm not sure I see the need for an extra low gear ratio. I've never even come close to needing more torque even in extremely steep climbs. And I find the accelerator control in climbing situations to be very good, too. Going down a bumpy obstacle, OTOH, I find it quite difficult to control my...

I use the term "lockers" loosely in this context to mean "software lockers" ie "better individual motor controls". I was actually pleasantly surprised how well the current software works in most cases. There's a lot of unnecessary wheel slip but mostly I was able to get thru the obstacles...

Our camping days are over but our R1T easily did the White Rim road in one day. White Rim is a very easy trail, just the thing for the Rivian. We also did Seven Mile Rim the day before. It was just about the limit of what I would feel comfortable doing with the Rivian.

I'm not sure when that happened but it was definitely not on Hell's Gate. I think I snagged a tree branch on an earlier part of the trip. No big deal: an off-road vehicle with no scratches isn't being used to the fullest :)

I stopped by there on Sep 27 just to give it a try. Worked great:
