Now here is a serious question:

I have lived in the US for a long time and raced on many different tracks and I have asked this question lots of time, w/o getting an answer.

Why are on road track in the States always built as a square and the lanes are divided by unmovable objects?

Especially in your country where you have so much room and where constructon work costs a fraction of what it costs over here, wouldn't it be easy to build a real track with lanes seperated by grass?

Most oval tracks I have seen are build this way.

Maybe somebody can give me an answer to this, since I am asked this question over very often.

Thx.
