More over does he even know how to drive? We never (that I can remember) see Mark driving and when he was a kid Nolan told him that he would eventually be able to fly so did mark go through driver’s ed in school or did he skip it because he knew he’d be able to fly somewhere if he want to go somewhere?
He probably never bothered since he’s an exception in the viltrumite aging process. It’s stated that viltrumite dna is so strong the offspring always has the powers so Nolan always knew he’d eventually awaken them and learn to fly.
