The one that TMP modified still can make you spin out, if your cab has relatively high HP and without a trailer (I've accidentally spun out on my way to pick up the event cargo, luckily I was the only one in the city). You need to be gentle with your accelerator when you trying to turn left/right, especially when you start after stopping for a stop sign/red light.
And in winterland with the physics mod, I'd say enabling automatic retarder and be gentle with your accelerator and brake pedal helps avoid skidding a lot (if you on controller or wheel setup).
TL,DR: The revamped winter physics mod can still be slippery, but not as much as last year with the original one from the mod author.
