Piwoslaw, I'm sorry to read that. But since you mentioned that other Europeans may have similar problems, I'd like to share that here in Bulgaria it's even harder -- we still don't have a way to make even an electric conversion legal. Our equivalent to your ITS has procedures for testing only ICEs -- no EVs, no aeromods
I wish you good luck with the ITS! And to all the people here from Central and Eastern Europe -- please keep trying to make the legal and tax changes in your countries, it will help us all in time
