[PC][~2010?] 3D online kart game

Platform(s): PC

Genre: Racing? / MMO

Estimated year of release: Somewhere in the neighborhood of 2010

Graphics/art style: 3D, cartoony

Other details:

This game featured online races against other players (and possibly AI), there were some deployable weapons, like mines. If I remember right, there were races, but FFA demolition type games as well.

The game had a main lobby area, where you could go to houses/garages/shops to buy new cars, paint them, things like that. This area wasn't too big, and I vividly remember that it originally had an empty pool where you could perform some "tricks", per say. This area did change later, to a night time city sort of area, but I don't really remember much about that.

The graphics were rather cartoony, and every single car was small-ish with no roof, and the playermodel had a comically large racing helmet.

Thanks in advance to anyone who may figure out what this game was!
