Cars do suffer from carb icing:
A) if they have a carb - modern ones don't, they are fuel injected
B) If the hot air intake system isn't working.
A few years ago I moved to a temperate climate (UK) and imported a Space Wagon car I previously used in the tropics. It didn't have any arrangements for a hot air intake fitted, out there it was obviously not seen as necessary by the manufacturer. In cold, humid weather it would get carb icing, even on the motorway. In slow traffic in town, if icing conditions prevailed it was a nightmare, it would cut out in the most inconvenient places!
The problem was solved after an articulated lorry hit it on black ice
