Finally home and got to spend the day playing with the car.
Better than Tesla:
Spacious feeling in front seats.
Luxury touches (HUD, ventilated seats, 360 camera view, hooks to hang my jacket)
Quiet.
Adjustable regen braking options.
Blind spot warning (I know many Teslas now have this, mine did not)
Cool factor (honestly, I didn't really expect the comments and questions). Also kind of fun at the Electrify America Station, visiting with all the newbie owners.
Free EA charging for two years.
Highway Driving Assist 2. Coming from Autopilot (not FSD), this is a plus because it does the navigate on Autopilot and the automatic lane change. Plus the park assist where it can pull in and out of a tight space. I've tried everything except the park assist. Works great!
Missing my Tesla:
That map, miss that huge, crisp map.
Walkaway door locks (very, very much)
Not having to press a start button. Just get in and drive. (amazing how lazy you can get)
Range (although I knew I didn't need the range of the S when I bought this car, so it should be fine. Have not tested it yet)
OTA software updates. Ioniq requires you download it to a drive and load manually. Supposedly they are changing to an OTA function, but not up yet.
Same-ish:
Fun to drive!
Audio performance
Storage for me (definitely smaller in the Hyundai, but I don't care)
Haven't tried yet:
Electrify America on a long trip
Service
I spent today driving it around. It was a great day.
