I did hesitate, when entering Portugal, whether to follow the estrageros (foreigners) instructions and log my credit card for the automatic tolls but I’m glad that I did. Three days ago, as I left the country, the border police took my passport and registration documents and checked that all was in order before letting me leave. I cannot imagine the amount of hassle that would have caused, all for fifteen or so quid I spent. You put in your card, the machine has already read your registration plate and it gives you a receipt. As you travel the motorways, the vehicle passes under camera gantries that automatically note that it is your vehicle and deduct the appropriate (displayed) amount from your card. No slowing and stopping at a toll gate, no scrambling for change and clambering to the wrong side of the cab to pay, no wondering if the barrier will close too soon. You just drive and it automatically does the rest. Big brother is watching you all the way.
