Where I am we don't get salted roads and a jacket would be a bit of overkill for me. Not to mention needing one for passenger.
Might be good in the northern states like the OP lives in but I'm sure the will be times where you go out it's light jacket weather then gets chilly for the drive home. Then you'll be happy that you opted for one of the most inexpensive options on the list.
Some people see not having one as one less thing to go wrong, for me a heated jacket would be one more thing to remember to bring.
