The secret to driving on snow is to never use your brakes. Once you brake, you lose control of your vehicle.
Braking can be done, but you have to 'pat' the pedal repeatedly, in quick succession. You are basically doing what ABS tries to, in that you get some braking, lose traction, but are off it soon enough for the wheel to keep turning and regain traction. Lather, rinse, repeat.
The GM model block my daily driver is from (late 90s) did this, but it cycled so slowly that you'd be through an intersection long before you actually stopped. (I pulled the 60 Amp fuse for that setup).
You can do it far faster yourself with better results.
The other thing is to give yourself plenty of room. Doing anything that changes the speed of your wheel rotation in a hurry will generally result in a loss of traction, whether it is speeding up or slowing down.
In town I start to stop for a stop sign half a block before I get there, because the last couple of car lengths tend to be ice from people stopping or spinning wheels when they go. Take your time, because the objective is to get there, not get there in a hurry.
Before ABS, we just used the quick pump technique, something best practiced in a parking lot somewhere with nothing to hit (how we taught the kids).
What make all this difficult is sharing the road with other people who will inevitably do stuff that puts you in a position to react suddenly.
Here, you can give them room to drive like idiots, (and likely call in when they go into the ditch), but in more urban environments they will crowd you and do dumb stuff. Just try to leave room enough for you to react and never, ever, tailgate anyone. Signal well in advance, and keep your head on a swivel.
All my vehicles have aggressive tires (AT style), front and rear, even the 2WDs. When I started doing this back in the '80s, I got some odd looks from tire guys, but I explained it like this: You do 100% of your pushing with the back wheels, but you do 90% of your braking and 100% of the steering with the front, so put 'em all around.
It wasn't long before I noticed other people started doing that.
I don't have 'summer tires' because I don't run studded tires.
I carry a gallon jug full of oil dry (kitty litter will do) for sheer ice to scatter in front of and as under the wheel as I can get it for traction in those rare instances when there is that too slick to walk on ice under the tire. It works. I rarely need it.
