Hmmm, maybe arcade-type, or family-friendly racing games?
- Sonic & All-Stars Racing Transformed Collection
- Sonic & SEGA All-Stars Racing
- Hot Wheels Unleashed
- Redout: Enhanced Edition (this one is basically modern Wipeout meets F-Zero, but it's very fast-paced, probably not for everyone)
- Toybox Turbos
- Riptide GP: Renegade (sort of a mix between Jet Moto and Hydro Thunder, and a bit of a Wave Race 64 vibe to it as well)
- Circuit Superstars
- Beach Buggy Racing 2: Island Adventure
I do not own all of them though, make sure to check their descriptions (or reviews, or discussion forum) to see if they can be played in multiplayer.
