Probably Transportation
European public transport and all that
I'm far-left on transportation, believing that transportation is a key human right, and that people should be able to freely transport with buses, trams, trains over the European continent. Even flight should be for free. It however should be taxed based on emissions, and it should also be progressively taxed based on how often you take flights in a year.
I also believe transportantion should be easy, and that we heavily should focus on public transportantion, while driving should be made more expensive, not driving itself but the roads... because of road maintenance, with an indirect energy tax.
I mean i have a lot of ideas on transportation, but transportation is one of the issues i'm most furthest to the left.
