Speaking of snow: In graduate school, I was driving through campus in a major snow storm (almost no traffic, almost no people out). I saw a woman exit a building up ahead and start walking down the sidewalk away from me (so her back was turned to me). She got to a diagonal crosswalk, and without any warning, stepped out into the road in front of me without looking first. There had been no indication she wanted to cross the road until the stepped off the sidewalk and into the road. I braked as fast as I could, anti-lock kicked in. I came to a stop just in front of the crosswalk with her glaring at me like it was my fault. She didn't stop before entering the crosswalk to make sure that 1) any oncoming cars saw that she wanted to cross the street and 2) they had time to come to a stop (especially considering there was accumulated snow in the road). I was the only car out there, so maybe she assumed there was no one around. I was driving a small off-road pickup (think toyota tacoma type truck with off-road suspension and aggressive on/offroad tires) -- my aggressive treads may have saved her ass. I was SURE I was going to kill this woman, but I stopped just in time. If I had been going any faster, it would not have ended well.
