Errrr..autos

I can't understand what are two-stroked autos still doing in this generation. It's a pain to drive behind them. It can get you mad almost instantly, making you drive faster just to overtake them. Hmm, it's high time for the Govt to start thinking about getting them replaced with 4-stroke ones or nano cars. Not only the sound, but they pollute much more when compared to other motor vehicles. Is the govt going to listen anyway..
(Today I drove behind an auto and the driver neither drove fast nor let me overtake him, so I enjoyed the rattling his auto made!)
