Snow Driving And Regen Braking

[aw113sgte]

Have you driven downhill in snow? You can’t keep your foot on the accelerator down a steep hill, you have to coast and/or brake gently. If the vehicle doesn’t let you do this and locks up the wheels itself, you’re SOL. Based on all the feedback, I’m glad some way of turning off the hard regen before I take delivery will happen as this will be our ski-tripper!

Yes, this morning. Yes I'm on steep hills. Full off accelerator caused wheel slip. That's why you let off a little to the limits of the tires, no different than gently braking in a normal car.

You know what’s even better than having to gently threshold brake every time you’re on a slippery surface though? Having the option to coast if you want. If you want to slow, sure, feathering regen is the same as feathering the brake. But what if it’s so god damn icy that I want to just coast, and be absolutely guaranteed that 100% of my traction is available for lateral stability?

You might just tell me I drive too aggressively, but I can’t count the number of times I’ve found myself coming into a corner a little hot, and the only reason I can make the turn is because of extremely gentle steering inputs, and zero throttle or brake inputs.

If you truly want to get 100% of the available traction, sometimes you’ll want the option to coast.

ABS systems aren’t perfect either. In fact, they struggle the most with ice. There are generally specific ice programs that have to be triggered in the ABS logic. Just Google “ABS ice mode” to see how many vehicles struggle with this. (Granted, you usually see it reported in the opposite direction, with ice mode being triggered when it shouldn’t be). But there’s no reason to expect it only errors in one direction.

+1 for coasting. I'll be really disapointed if this unnamed new mode doesn't allow a full off option for regen. Which was my feeling even before a puckering moment almost taking out my mailbox last night.

I won't own the car long enough to find out, but considering how aggressive the regen is, even in snow mode update, I would not be confident. I see more teslas spun out on the side of the road in the Sierras during new snow than any other car. Most people's natural reaction during slippage is to come off the gas which depending on the speed and conditions would put them into a spin, or just right into an embankment. It would be real nice if Rivian would put blended braking in their cars. Even if it isn't perfect.
