Tight layers never a jacket precisely for that reason. Driving with a coat is ridiculous like driving with a straight jacket on, never understood how driving with a coat on can be comfortable lol.
Try it wearing a tee shirt, long john top, long sleeve shirt, brown hoodie and a winter jacket all at once. Add in gloves, mittens if its brutally cold, long john bottoms, don't forget regular underwear, long pants, a thick pair of socks and winter boots and a stocking hat that makes your head itch something fierce. I've also a few times worn Carhart contractors bibs over all this. Now you are in for a fun day.
