Off to France Germany and Switzerland in a couple of weeks. As any european traveller will tell you the pay stations on the payage are not Z4 friendly unless you are over 2 mtrs tall ( I am not nor the other half) What I discovered after my last trip was that you can buy the tag for the drive through channel , The costs for your trip are then paid via D/Debit .If you are travelling through France its well worth getting one saves all the hassle of getting out or hitching up to reach the c/c slot. Also as most vehicles seem to stop and pay every time you are not held up in the queues waiting to pay. Great if your travelling during the french holiday month.
