Tervuren , this thing existed before Indianapolis had the Brickyard
i guess it doesn't lend itself well to racing an ideal line does it?
and untill 1922, there were only 2 ovals in the world
Indy and Brooklands...
so in any way , Indy was not exclusive, it's not like the US drivers had ANY advantage in learning how to corner, it's not like there was a big racing scene in the US , there are no really big 1910,20 or 30''ies classic races in the US like Le Mans, Mille Miglia , Targa, Eifell Rennen, are there??ok , Indy500 itself , but it's still a weak event compared to any of those i just mentioned...
Europe is where the bulk of the racing happened, so to say European racers were crap at cornering and we only figured it out from lookign at you boys, is about as accurate as saying that Muscle cars always cornered better then anything Porsche ever made...
