I've done that with my FWD Patriot. Bet the Chevy you passed had those 3-season tires I mentioned above. I've got in a rough situation with our old FWD Saturn and I blame the tires. Barely climbed the grade on a snowy interstate. Granted the weather forecast was wrong, the DOT was caught flatfooted, and the highway was a mess. Still, I think a set of real snow tires would have taken the angst out of it. With good snow tires 3-4" of snow shouldn't stop traffic, but it did. I think a lot of drivers were relying on 4wd and 3-season tires. Much better off with 2wd and the appropriate rubber. JMO.I drove by a FWD Chevy cruise stuck in 6 inches of snow going up a 6% grade near my house as it if was summer. AWD/4WD may not be "necessary", but when nature throws a major winter storm at you, then it's nice to have it.
