Games similar to Motos?

[OdiousTrident]

I'm thinking of games like Motos, Pac-Motos and Hyper Marbles that involve a top down arena in which vehicles of different sizes and speeds try to knock each other off the edge of said arena.

Any other recommendations besides the 3 games listed?

Kenta Cho's Mucade instantly comes to mind, although the vehicles are snake-like in nature.

One of the Super Monkey Ball 1 or 2 modes (GameCube)? Or was it in Super Monkey Ball Jr. (GBA)?

The streetpass game in Super Smash Bros DS is similar.

There's a fairly obscure Naomi game that fits the bill exactly. It's called Ring Out 4x4.

Monkey Fight is that Super Monkey Ball (2 and onwards) mini/party game.
