Use A and D to move left and right to see the 3D effect in action! Also, press W and S to make a cool but completely useless effect.
I'm still trying to figure out Super Scratch Kart's 3D engine. This won't work, but it ended up being a cool concept anyway. There's a little issue with the road curving (kind of makes a hill), but it's still pretty cool. UPDATE: I made a way better 3D effect, and I'm making an engine out of it. Find it here: https://scratch.mit.edu/projects/167607780/ In case you're wondering, it uses a bit of weak perspective projection to make the road. EDIT: This is kind of technical, but I've realized what the distortion is all about. Turns out that it's a form of hyperbolic distortion caused by the nature of converting the matrix multiplication into simple linear equations, because z is in the denominator...
