I just also ran into 1st time with snow.
I found settings that made a lot better in snow.
Turn on chill mode and standard braking.
P85 doesn't get chill mode
Ouch. Probably all about the tires, but certainly a hairy moment. Which "high performance all season" tires do you have on the car?
Primacy MXM4s. I went in knowing they would suck, but they still sucked more than I expected. I'll likely sacrifice a bit of range in the summer for being able to actually drive in the snow, come next tire change.
