There are some propane based cars and Go-Karts.

可能还有些烧丙烷的汽车和卡丁车，但一时半会也搞不到。

Morley: Should we go race go-karts or does anyone need to do some shopping?

莫理：我们要去玩小型赛车或是有人需要血拼一下吗？

I'm going to Europe to use the simulator and drive some go-karts and then I will know very well if I'm 100%.

我要去欧洲，使用模拟器，开一段时间卡丁车，这样我就可以知道我是否已100%好了。

In actual honestly I was racing go karts in Brazil just to keep fit.

事实上我只是在巴西跑了卡丁车来保持状态。
