The garage gives each race a little more purpose. Unlocking another car can make familiar tracks feel different, especially when tighter bends and jumps start demanding a change in driving style. The pace stays fairly breezy, making it easy to settle into a few races without overthinking things. The full version is unlocked.
Scenery opens up alongside the progression, while collecting cars gives the racing a small but useful sense of direction. Nothing feels needlessly elaborate here; it works nicely as a pick-up-and-race sort of experience.
