Also at stop signs cars heat up the packed snow which again melts and turns into ice. as someone said above, you can’t do much with ice and you did well all things considered!
Btw think it is criminal they didn’t rent you a 4WD especially coming from SoCal.
To follow up, the only “safe road” is a dry road in the upper Midwest. So if you encounter snow on the road at night, think ice.
Also if you’ll be traveling again there, look out for lakes. Snow squalls can happen any time it is cold and windy—the wind picks up the lake moisture and blows a white out blizzard across the road with no warning.
