Anyone else know a way round this other than asking a french person to card it and pay them the cash as i reckon my chances of that happening in the wee hours are minimal.
The way round it for us is to fill up a load of petrol cans in the UK and hope for the best!
In the past we have left Le Mans on Sunday night, and then slept the night wherever the first car ran out of petrol! With a full tank, and about 15l in cans, we can make it up to the Rouen area.
