The level is adjustable. I keep mine on High, it's generally enough to stop even at yellow lights without hitting the brakes. I'm guessing there's a chance the lower settings have an energy limitation, which is why it felt inconsistent. It requires taking a lot more energy to slow at high speeds vs low ones. Even towing a trailer I rarely have to hit the brake pedal.
That's funny! When we sold our 2015 Nissan Rogue, the couple who bought it took it for test drive; it was going to be the wife's new car. They sat up front, I rode in the back seat. The car had that "lane departure warning" BEEP BEEP BEEP when the car would drift out of the lane. She was like "WHAT THE HELL IS THAT!", I calmly responded "That's the Rogue telling you that you are drifting out of your lane". The husband snorted, stifling his laughter, then told her, "...I guess you can deactivate that", then shot me a that glance.Weaker OPD makes it easier to drive smoother if someone doesn't have great throttle control. I wish the Rivian had weaker OPD when my wife is driving!
Brake assist doesn't step in when regen is too potent. It steps in when regen is reduced to help maintain the same level of slow down regardless of how much regen can be utilized.
Undriven for a year, took out my glorious Tesla Model Y Performance for a spin today. If Rivian's regen implementation is the yardstick, regen braking on my beloved MYP is just as strong and excellent as, if not better than Rivian's. Perhaps regen has changed in Tesla later models.

I'll counter your anecdote with my own, my 2018 Model 3 SUCKS in so many ways (including UI [excepting texting!]) compared to my R1T, particularly in the body corrosion department - this thing looks worse at 7 years old than my 15 year old Subaru Loyale when I was in my 20's.
