I definately agree with this, on usual public races there's problems with large grids which is even worse on small tracks due to constantly having to lap slower cars. But no matter what track you're on, larger field makes T1 mess even more likely and I got fed up with whole restart vote spam everytime someone crashed out. Thankfully it seems that there's more and more servers which have it disabled.
But on the otherhand, I've also had some great racing on Lime Rock Park which is only 2,5km long circuit and Formula Mazda completes a lap in 46 seconds. Combining that with 20 car grid which makes competition very intense and you got yourself 45 minutes of adrenaline rush.
