If anything we should at least get ABS engaging sounds, which at least in the older trucks I used to drive were loud and menacing enough to make you rethink your driving strategies.
I can live without the suspension kneel, especially on the trailer since I don't see it while driving in cab view. And it's not easy to get right either, even Snowrunner which has locking brakes pushed to extreme, doesn't simulate trailer behavior correctly. But it would be nice to get that sound, letting you know, you effed up.
About 1:46 on this video.

I want that kind of sound from the trailer.

And look at this cab rock:

This is the stuff that makes a truck cool to me. It's big; it's loud; and it moves and bounces like no passenger vehicle ever would.

We can agree current game version is unable to pull it through?
It needs to be implemented first

Yeah, that's a better way of putting it, the current physics system can't do that

Example: this Volvo jackknifing on a slick road. Tires aren't stuck to the ground like they are in game.

The truck I used to drive never did have ABS on the trailer. Every time I hit the brakes, the trailers ABS light as well as a light on my dash for the trailers ABS would light up. All I could tell was some kind of software issue in the truck's computer wouldn't read the trailer connection correctly. As such, I have figured out ABS is quite useless. If the brakes are locking up, the simple solution (which is the exact same one ABS has) is to let off the brakes for a bit.

ABS is probably much "worse" in trucks simply because they are on a vehicle 80 times heavier.
It's not that they are worse, but rather that the brakes are under much more stress than those in a car, ajd much more prone to locking up, which gives the ABS more opportunity to mess up. That said, the weight of the vehicle can often help you stop in these cases. The main issue with locking up brakes isn't the lack of stopping power (the wheels aren't moving, so you theoretically have the highest possible braking power), but rather the vehicle "hopping" across the road (like a rock skipping across the surface of the water), so the wheels are no longer in contact with the ground. A loaded truck has a harder time doing this because of the weight, so your locked-up wheels have more contact with the ground.

Basically, ABS is more likely to fail in a truck than it is in a car, but this is less likely to prevent the vehicle from stopping.

While ABS exists exactly to prevent the brakes from locking up and the vehicle sliding, they are not 100% effective, and very often fail to prevent it.

Guess crappy ABS is an American thing then. Cause in the trucks I used to drive back in the day when ABS was more of a novelty rather than the norm, it never failed me. Mind you I only used it a couple of times on various trucks and more as a sort of "finding the limit" rather than full on emergency, but still, it was working as intended.
The smallest details always make the biggest difference.

They work as intended, which is not 100% effectiveness, because that is simply not possible. Nothing is 100% effective.
If you only tested it a couple times, you lack enough data. Any vehicle with ABS will most likely work at least a couple times.
Even in my truck that practically didn't have ABS at all on the trailer, it still worked a few times here-and-there.
If you made use of it more often, you'd probably hear a bit of skidding, but not notice much distance, compared to cars that will skid and hop a few hundred feet on locked brakes.

every truck and trailer has ABS (well it is called EBS and it is mandatory on ever truck+trailer) and it works 100% of the time, if it doesnt it means it is defective or the sensors are broken, its job is exactly to prevent the locking up of the wheels (the EBS version is even so advanced it locks/unlocks the brakes depending on the wheel many times a second) also all our newer trucks and trailers (at least the last 10 to 15 years maybe more) are equipped with disk brakes, there is no drum brake not even as option for all i know, this can also be a big factor, also, the weight of the vehicle is irrelevant for the ABS, it just checks if the wheel is rotating or not, if not, release brakes to get it rotating again
