Well, these problems do publicly rear their ugly head in cars intermittently. Telsa pushes out recall-worthy software updates, Toyota had its infamous stuck accelerator pedal issue in 2009, etc.

The airline industry gets such a weird amount of public attention across the board ranging from passenger safety to massive investigations if a plane goes down. It's not necessarily a bad thing but you certainly do not hear federal regulation stopping people from driving a model of car (recalls yes, but nothing akin to grounding) if there's one unexplained crash.
