I grew up in the South so I can pretty much avoid heat stroke.  Maybe.  When I moved up north I had no winter knowledge, except those that people would tell me.  Not all was relevant or useful, and I had to figure some things out for myself.  One big revelation: Driving on freshly fallen snow is preferable to cleared pavement.  I had more traction with the snow for turning.  Go slow, manage speed, and avoid sudden actions.  Winter tires were a godsend.  If I didn't have those, I'd probably have died.
