I upgraded from 2018 S to 2021+ LR. The 2018 still had the option to switch Regen from Normal to Low, and I always used Low when spouse was in car because she felt some motion sickness if I wasn't careful with the go pedal.
So I was concerned that 2021+ no longer has Regen option, and that this would create a problem for us. Fortunately, we have both "felt" the new regen is much smoother by default and with normal driving my spouse doesn't feel ill. For example, when you take foot off pedal at speed, you don't feel the same lurch and it's easier for me to manage the pedal for gradual deceleration without thinking about it.
I also *really* love how car will come to complete stop and auto-hold at red lights (without using AP). With proper pace and distancing one can avoid using the brake much. Of course if you want to feel ill, you can always stomp on the go pedal for that roller coaster feeling!
