I love the look of the Ioniq so much, I wanted to reward the guts it took to create such a unique looking car! I wanted to buy the new one but I just couldn't not get a Tesla because of FSD. Cars without FSD are fighting for second place imho.
With Tesla it's all-or-nothing, and when it inevitably drives poorly, I can only turn it off. It physically resists me turning the steering wheel while it's driving, and overcoming the resistance results in an unpleasant and potentially dangerous jerk.
OTOH in IONIQ I can control lane assist and adaptive cruise control separately. The lane assist is additive to normal steering. It doesn't take over, only makes the car seem to naturally roll along the road.
The N-line is Hyundai's high-performance designator, like Type R for Honda. It has way more power than you would ever need for normal driving, hopefully to be used on a track and not street racing. The normal Ionic 5 has no faked engine noise (beyond the low-volume external sounds required by law).
There's probably a federal or local law requiring some sound. Like the Waymos that incessantly beep beep beep when backing up at the recharging station at 1 mph. You're about five years away from hearing beep beep beep everywhere you go due to the proliferation of driverless vehicles.
