I think OBU has other objectives besides money making. too early to analyse the implications and effects. But we can speculate with whatever limited information pap is willing to releaseIt’s complicated to be charging for so many different things and having so many different bills when all can be lumped into a single bill.
Road tax and ERP could well be integrated into a seamless process with a single component, the OBU seems to be a good candidate, don’t you think?
