Creator Cars and Minifigs

Out of curiosity ~

I'm trying to find some extra cars for my Cityscape and was wondering...

Are these Creator Cars minifig scale?

#31017 Sunset Speeder
#31002 Super Racer
#31006 Highway Speedster
#6913 Blue Roadster

I know some are 8 or more studs wide.
Will they accommodate a minifig 'as is'?
