Why hasn't tour racing become big in the States?

May be...

yanks can only watch round ovals and its boring nascar .check out our racing in aussie see link 1000km road race

Check with your local track for SCCA events or the American LeMans series.

Because we like watching things go in circles.

I think they tried to get a touring series going like the one they have in Europe. It just didn't catch on. We do have plenty of touring car racing, but it's just a bit different.

There are the British, World and German Touring Car Championships (BTCC, WTCC, and DTM) which are excellent! I am not sure however how you could get to watch them on US TV. I know that Eurosport and ITV4 show BTCC, but don't if they stream to USA.

These guys do turn right very well! I guess it's not so big across the Pond because NASCAR is the main motorsport watched there. Here in the UK, I get to see F1, GP2, WRC and touring at the very least.

Sorry I can't be of more help and I really hope you find a way of watching it. It's brilliant. :-)

Americans don't like it,
but i would really love it if there was touring here in the states

And if it has where in the world do i find it?
I live in Texas and i've only been able to find NASCAR (left turn!! LEFT TURN!!! FASTERR! HIT IT WITH A HAMMER!) and like lawnmower racing.
I would really like to watch a real touring race.

America has NASCAR and the Indy 500, and i have to admit, Indy car racing is the sh!t

You would probably be able to watch it only on tv. Basketball, football, and baseball (in that order) are the sports of choice in the US.bizwire
