I drive a Toyota hybrid, and have never even remotely considered relying on regenerative braking to even slow my vehicle. If I want to slow down, I press the brake. If there's any slowing because of regenerative braking, I have never noticed it.
You're right now that I think a little harder about it. I used to have a 2006 Prius, and though it did charge the battery while coasting, it wasn't anything like Tesla-style one-pedal driving. I was in the habit of shifting to B while coasting down the hill where I lived, which is why I have the memory of regen braking while not pressing the brake pedal.
Pressing the brake on a Prius will use regenerative braking. It only switches to friction braking if you brake extra hard, or the battery is already charged.
So there's no need to "avoid the brake pedal to use regen" the way it sounds like these Bolt drivers are doing. Which seems really dangerous.
