I have viewed all the threads on this subject and as an outsider understand the frustration of the locals. They definitely got attention and hopefully get attention in France. It must be frustrating for them to hear tourists saying there must be an other way (which will not affect their visit) without actually suggesting an alternate solution.
Personally I would like to know how tourists can help in sending the message to the French government that the PLU needs to be amended in favour of the locals.
