President Joe Biden’s visit to the Detroit Auto Show – aka NAIAS – closed the show floor for hour upon hours during what traditionally was an exciting and new-product dense press preview day.* Well, that was once upon a time. Media day used to start the lead up to the paid-attendance public show days in an attempt to spur buying interest during the dark days of Michigan winter.
