[Disclaimer: I wouldn’t know a Hyundai Sonata from half-baked ricotta. They are not sold or rented near me.] However, I do drive.
Do you have to sit so straight?
What happens if you recline the seat back a bit? Does that bring your head off the rest?
Could you adjust to driving like that?
Is it like my GM cars that allow tipping the entire seat (lower cushion and backrest together) to the rear a bit?
Have you talked with Hyundai sales/lease staff to get some ideas as to how folks drive those things?
