Simple premise, great graphics, but vehicle tiers are based on coolness and not any actual performance capability (4WD car that does a 4WD burnout with only 300 HP, but the same car with a slightly different body is three tiers higher? Sus) Game uses time gating with the fuel system to prevent rapid progression, so you only get a couple actual minutes of play every other hour. Advertisement system breaks often, and causes problems with game assets not loading on occasion.
