Generally nothing happens if you are on foreign plates. DVLA are happy to sell your information to all and sundry yet other countries seem to be a bit more careful as to who they give their citizens information to. As an example go through the M50 toll in Dublin in UK registered vehicle without paying and you will get a bill through the post, go through a speed camera in the UK in an Irish registered vehicle and nothing will happen.
^^^^^^^^^^^^^^^^^^
theres no barriers,no info to alert you to go and find the nearest spar shop to pay your toll,you never entered any form of prior contract with the m50 toll so they sell your reg to a debt collection agency in the uk who send the normal type of mega prosecution if fine not paid type letters,but they have no legislation to enforce a civil action from another foreign country as they are just a uk debt agency.
every time i go through in a uk reg then i usually get 3 or 4 for a few months,then nothing.
dunno if it works across the board,but ive always just ignored till they vanish.
