Nonsense. Retain a reasonable buffer to the vehicle in front and you won't have that issue. An EV with one-pedal drive begins decelerating as soon as the accelerator pedal is released. That means anytime you're not coasting or speeding up, you're automatically decelerating. If anything, that makes emergency stops safer, because the vehicle slows as soon as you identify the need to slow, before you actively transition to braking.
I run my Cadillac LYRIQ on High Regen and I’d generally agree. If I come off the accelerator quickly - like in a panic - it starts slowing instantly and noticeably.
I love One Pedal Driving, another thing that makes driving EVs so great vs. ICE.
