> The EV slows down much more quickly when slowing down, to the point where it's a good replacement for the brake

Are you comparing to an automatic ICE or a manual?

In my experience of driving EVs their engine braking is sub-par to what I'm used to at least from my motorcycle. Bikes have silly high compression compared to their weight. You def have to be careful about chopping the throttle.

An automatic, with a manual you can shift down to whatever you want, so there's no standard there, really.
