We're off topic here, but I guess that's the norm for this forum.
You teach in a very different environment from me. We don't have winter weather to worry about here, just rain sometimes. So, my students won't ever feel ABS unless they're braking really hard. And it's very much urban/suburban here. I have to make a special trip to get "out of town" to do a lesson on curvy back roads... which I do when I can. (otherwise, I have students who know how to drive straight and drive 90 degree turns... but, slow to a crawl for any curve) Teaching on ice and snow would be somewhere between really fun and terrifying depending on the student! But, I guess that's the nature of the job, in general.
I preach the heck out of "drive smoothly" from the very first lesson with every student. We do cover quick stops and ABS as early as they seem ready to learn it, but the way I expect them to drive in the real world is to keep proper space, OBSERVE, and react to things early enough to be smooth. "Put on your limo driver hat, don't spill the boss' martini in the back." But, also "smooth doesn't necessarily mean slow", we're still getting where we're going and not holding up traffic.
I used to hate ABS, too! I especially hated older "cheap" ABS, like the "rear only" ABS on some 90's pickup trucks, or the "3-channel" ABS on cheap 90's cars that had separate channels for the fronts, but both rear tires on the same channel.
Stupid 90's ABS anecdote that Mirage Rally will probably appreciate:
I used to be into Saturns when I first started autocrossing. Mine didn't have ABS, but I drove a friend's that did. If you've ever done or watched autocross, you know that FWD cars have the strong tendency to lift an inside rear wheel under hard cornering. Well, Saturns do that, too. And I was used to my Saturn. I could fling it into a fast sweeping turn, and still brake a little to scrub some speed if I needed to while entering that turn. (the turn in question was a decreasing radius turn) Tried that in the ABS car. Fast sweeping turn, right rear tire lifted. Tapped the brake and got NOTHING. Because the unloaded rear tire instantly locked, the ABS must have thought I was on ice and was waiting for that locked wheel to start rolling again, which it didn't do until started straightening up. SCARY! Fortunately, I just hit a couple cones.
I've since made my peace with ABS because the technology has gotten a lot better. Plus, we kinda don't have a choice any more. All cars have it.
