Last time I looked all cars in Florida had rear window defrosters and nobody seems to complain.

Just odd that they base the inclusion of heated seats/steering wheel on AWD.
As for being garaged you are correct however it is highly unlikely they go to work and garage it there also. You are obviously speaking from a retired persons position.
My daughters Elantra has them and so does a Kia Soul, heck they even get heated steering wheels just like the Honda I bought. In fact the Honda is actually better equipped than the Genesis minus the HUD! These are not big ticket items by any means when they appear on entry level cars as standard equipment. Just poor judgement on Hyundai's behalf IMHO.
Speaking of the Honda I bought, there are several items not available on the US yet are standard equipment in Canada. Why do we get ventilated front seats yet the US not? I am sure Floridians are quite ticked off. It's just as cold in Michigan yet they cannot get heated rear seats! Another thoughtless decision by an auto maker IMHO. Here is a quick list of them and most make no sense at all.
- Heated windshield wiper area
- Ventilated front seats
- Power folding mirrors
- Rear climate control panel
- Heated rear seats
- CD player (accessory for US models)
- Rain sensing wipers
- Dual note horns
- Turn signals in the mirrors
- Splash guards (accessory for US models)
