We need a snow driving mode

[Adventureboy]

This is my third winter in all kinds of slippery, snowy and icy conditions. I use Standard mode in OPD with proper winter tires and love it. No additional mode is needed. The traction control works awesome in slippery conditions and we get really icy conditions here. As with any vehicle in the snow and ice, slow and easy movements on the pedals make all the difference regardless if you use OPD or not. Just know not to take your foot completely off the accelerator if you hit a patch of ice. Same method as driving a standard transmission with ICE.

Keep the rubber side down.

Though not critical, I agree with the OP that this would be a nice convenience feature. My EV6 has snow mode as well. It also had paddle shifters you could dynamically adjust regen levels with. I actually used them a lot, it was akin to downshifting a manual.

First winter with an EV and I love one pedal. I thought I would have to switch to two pedal for the snow, but I’ve been impressed with how well one pedal works. To me it’s more about the operator being “smooth” than the actual vehicle having a special mode. I’ve never liked snow, mud, economy, etc. in any vehicle. I just adjust how hard I stomp the pedal!

I do exactly the same and never use one pedal.

Well, not exactly the same. I heavily preferred 1pd on even in the snow.

This, and turn off one pedal mode!

Why though? It works so well...

Task management, or in recognized pilots terms, task saturation or cogitative overload.

Very often in slippery conditions you just need to coast down, either from an upcoming situation, or because traction for steering is more important than accelerating or braking. With 1pd drive enabled, NOT braking requires cognitive load. In essence part of your focus is now forced to manage the accelerator when that focus could be better utilized elsewhere. And I know its easy to claim that this isn't an issue, and for most on an empty road it isn't. The issue is that in a developing situation, such as an accident ahead on the highway, a LOT is happening all at once. And unlike simply sliding a bit, instead now the driver is trying to process all of those things AND also trying to NOT brake and NOT accelerate.

Not saying its impossible but having delt with a lot of snow driving quite frequently it is a lot more than simply "don't slide".

I just wish we had snow, period.

While I understand your premise, feathering the throttle stops being a noticeable cognitive load after practice. Just like in a manual vehicle after driving it repeatedly you find yourself shifting gears without realizing that you’re even doing it. I don’t have to think about not braking, by this point my body knows the amounts and I adjust.
I drove in 8ish inches in WV a couple weeks ago and had to deal with coming down a mountain as well as multiple spin outs occurring around me during the trip. I would still use 1pd every time.

I am not saying that it’s the right choice for everyone, but there’s too many people saying that turning it off is definitely what everyone should be doing.

Reducing power output in the snow is easy - just drive around with a cold-soaked, mostly depleted battery!

In all seriousness I like a bit of regen in slippery conditions as it "feels" like downshifting in a manual transmission vehicle - scrubbing speed without disrupting weight/balance like friction brakes can do.

Another pilot adage is don't change how you fly for your check ride. If you normally use 1PD and switch to 2PD during hazardous conditions your muscle memory may revert to "normal" or you may conflate the two modes in the heat of the moment.

All that is to say, use what you are comfortable with and drive slow enough to avoid loss of control situations or give your brain enough time to process if you do find yourself out of control.

I don’t think that’s correct. I’ve had advanced driver training due to being in the fire service.

I can drive the Lightning in the snow. I’m just saying the Rivian snow mode makes it levels above the Lightning in the snow.

I was pretty happy with my Lightning in the snow, in upstate NY, in 1-pedal mode, this weekend. I do have snow tires, though.

While I do agree with you and @Henry Ford in that using it breeds familiarity, and for those that use it frequently they will be better set up for how to react in any specific situation.

I do want to point out though that being familiar with it also includes using it and being familiar with it in that particular situation, not just general use. Heck, this is true of regular driving, many run into issues because they don't know how to use the regular brake pedal in the snow, even though they use it every single day. So certainly not something specific to 1pd driving.

I'm certinaly not saying that nobody should use it in the snow. But with many users having this as their first electric, many not using 1pd exclusively, and many jumping back and forth between regular cars and the lightning, the better approach for them may be to revert back to 2pd driving.

"Snow Mode" could also disable all the alerts that my cameras and sensors are frozen over, and maybe even change the color of the screen to remind me that my sensors are useless instead of beeping at me every few seconds. Point is, having a single button toggle to do these things would be a nice to have.

I get your train of thought. However, I‘ve been driving 1 PD since 2 weeks after getting my MME 3.5 years ago. except for borrowing a 6 speed manual a few weeks while some repairs were being made and a week with a loaner while getting recall action completed.

so, 2 PD is cognitive load for me. I know my brakes are there and can use them if needed though I frequently I do not.

I live in upstate NY and we are just digging out from the storm yesterday.

During the storm I took my wife’s Rivian out for a spin. I found it had a snow mode where it lowers the aggressiveness of the regen breaking and lowers the pickup to avoid the torque spinning wheels and sliding the truck. The weight of the truck, all terrain tires and the snow mode made the Rivian snow driving a dream.

We really need a snow drive mode for the Lightning. I’ve definitely found myself sliding because of blipping the throttle too hard or stepping off the gas to quick and the regen kicking in. It feels like it could be done as a software update.

While I don’t mind the concept of a snow mode, I would much rather them provide us an eco mode before a snow mode. That setting I can use year round and see some potential energy improvements too.

I enjoy the greater efficiency I see in my M3 in Chill mode and my daughter’s og Ioniq’s Eco drive mode.
