He he, even in the world of 1:1, there is buggy同平跑, they may not be a big difference if you play on street/playgroung, but if you go to track once, you will know the difference.
平跑 can hardly move on buggy track (not to mention about jump), buggy will run very slow on 平跑 track, easily roll over, and "shoot " by other 平跑
