From my experience of driving in Europe...Spanish police seem OK, French Police are B*****DS.. they gave me an on spot fine ,,,then about 4 months later I had a baliff at my door at home !! telling me they didnt fine me enough at the time, as It had now gone to their court, and would I pay more money.. The answer was a no, with various expletives..never heard anything more about it ( but I do tread carefully in France now though,just in case it's still on record )
