I've lately been playing Redout (Redout: Enhanced Edition) on the Steam Deck, and it is a quite fun game in the spirit of the old Wipeout game. Consider giving it a go if you are into that sort of speed-over-everything-else racing games!
I've been also enjoying GRIP racing, which while it's a bit more conventional and has wheels, (follow up to Rollcage) gives me similar pleasure. It's very fast, simple, and the gravity is often just a suggestion.
