It's a bit off-topic here, but some more arguments or view-points for "too many rallies in the same region" and "car market is not big enough":
* corona - at the moment rallies are where someone is able to organize and deliver them, car market is not important
* previously Rally Estonia was not imaginable because "it's too close to Finland", now both are in calendar - car market in Estonia basically does not exist, it's equal to rounding-mistakes for big corporations. What is important - fans, attitude, environment, will to provide. I remember some sentences like - "finally rally is moving to places where it belongs and where it must go - close to fans and areas, where it's important and expected". You may organize rally in some "big car market country", but if nobody cares and it does not get media attention there, then what is the point?
