There was no "Accept" option when I tried, so only option was pressing B.
I do appreciate the style too, kind of reminds me of the likes of Top Gear and Outrun.
A simple arrow around the top and bottom edges of the border of the options menu should be a hint for "more settings above/below".
Another thing I noticed is that even on Easy Mode it feels impossible to get first place with Captain Falcon, so once improved steering ideas gets added it should make everything more feasible
