What regen mode do you use?

[usulio]

I am a little disappointed that this is the only small part of my original comment that is quoted. As I stated I am historically a single pedal driver from my stick shift and Motorcycle beginnings. In the end I use the break pedal no more in low regen as I did in high regen. My main point of my original comment is even in the highest regen setting you are getting back a fraction of kWh that you use with acceleration. I found that the high regen was slowing the car down more than necessary requiring me to use the acceleration even more to combat the regen, which in the end is using more energy. The lower regen is allowing the car to freely coast a little more with out extra acceleration which should use less kWh. I do not know exactly how much the pads were used in breaking but in my Volt, and my Tesla the regen did work on the break pedal unless you stood on it hard. Neither of those cars ever needed a break job.

My Leaf works the same way. Nothing against your comment, just trying to learn the facts (something Rivian does not make easy).

High unless my passengers are getting sick. For avoiding car sickness, low Regen and AP low with firm dampers helps a lot. I usually modulate braking in all modes, but it's a lot easier to be smooth on low Regen mode.

I used high since I got my R1S, but I just had to get new tires at 16k miles, so I switched to low to see if it will make any difference on tire wear (it probably won’t, but worth a shot). I am still able to stay off the brake 95% of the time.

Try not to be disappointed. These comments aren't a reflection on you at all. Although this isn't Wikipedia, we still try to understand what is and isn't true (or likely true) in the interest of helping anyone who might be reading these things in the future. My concern wasn't with you. I accept that your experience was one where you don't feel you use the brakes when you step on the brake pedal.

The concern was with trying to figure out if all of our vehicles do this, and whether or not they do it intentionally or if it was just yours. There may be something wrong with your vehicle as it seems that the brake pedal should actually engage the brake pads. There could be something wrong with mine in that my brake pads engage immediately.

I'm just trying to figure it out.

For me adding a bit of "accelerator" pedal while slowing down in regen doesn't actually use acceleration or actually put power to the motors at all. It just causes the motor to not generate as much electricity and thus it becomes less resistive and the car doesn't decelerate as quickly. I don't think Rivians are designed to use more electricity when you slow down less rapidly. They just don't regen as much.

But it’s the 1st vehicle I’ve ever driven (other than tractors/combines etc) where you have to lift your foot over to the brake pedal, which to me is severely dangerous, particularly given the fast & furious nature of LA freeway drivers that will jump in front with a fag paper’s clearance.

Why would you hover on the brake? As soon as you lift off the accelerator it will slow you down, so the argument 'I'm faster if I hover' seems to be invalid. Normal reaction time, paying attention, and the car slows itself before you can touch the brake instead of coasting at the same speed until you hit the brake.... This all together seems to imply that coast and hover is not nearly as quick of a stop as one pedal driving then moving to the brake when someone does something stupid...

I have been using high regen setting using AP drive mode for long time (2+ yrs). Couple of weeks ago, I decided to try out standard/middle regen setting, and found out that it's a lot easier to drive. The high regen mode requires rather steady pressure on accelerator to stay in the narrow pedal travel for coasting. It's much easier to achieve this coast in standard regen mode, and I haven't noticed any significant decrease in efficiency. I also haven't used brakes any more either, and the ride also seems smoother for passengers. I recommend giving it a try if you're on high all the time, and haven't already tried it.

I've only used high in a lot of vehicles after trying out the other modes. High isn't too harsh as long as you modulate it with your foot. If you want to easily coast, then be gentle with the foot. It's as gentle or as aggressive as anyone could hope for if the foot modulates properly.

The sensitivity of the pedal travel is what I don't like about the high setting. The pedal modulation seems to take more effort to maintain a smooth ride.

I want something in between.. standard with max regen if I completely lift foot off accelerator.
