"Proof of Insurance", thats going to "impact" International competitors,, my experience in trying to obtain Accident Insurance is that you can get it, BUT!, at an "Exorbanote Premium",, most International racers that i know have run without and have to suckup the conquences, however now that proof is required, i guess thay will leave their vehicles at home unless somewon can come up with an affordable short term coverage,,
I choose to run FIM as thay offer/requier Insurance before thay issue you a licence,, thay nominate their Insurer who offers a reasonable rate,,,
