A free student game called "Nitronic Rush", and then "Distance" when the devs were able to expand it into a bigger game
Basically you drive a car with rockets and shit all around it (and also it can jump and fly, because of course it can), so you can boost yourself forward but also control your pitch and roll and stuff and press yourself down as well, and you have to race on tracks filled with buzzsaws, lasers, etc. while also using those rockets to flip your car around and jump to roads that are sideways or upside-down. It takes some getting used to, but once you have the hang of it it feels so good to be dodging obstacles and doing what feels like a cross between car parkour and air acrobatics
...I still have such fond memories of practicing the hardest tracks of Nitronic Rush over and over until I knew every twist and turn by heart, but nobody ever seems to have heard of it, or Distance for that matter
