Many British motorists caught on Speed camera's, while on holiday on the continent have come home
to a hefty fine for the first time this year.
It is estimated that half a million UK motorists will face prosecution for driving offences in France alone.

In many EU countries including France, responsibility for paying the speeding fines lies with the vehicle
owner who might not necessarily be the driver, at the time of the speeding offence.
Whereas in the UK, the responsibility lies with drivers rather than registered car owners. This means
that by a quirk of law, UK police will still not be able to fine drivers from the EU.

Breaking speed limits by more than 31mph can result in fines of up to €750 under reforms, which came
into force in 2015.

The Telegraph - British motorists face £640 Speeding fines this year

Hi,
Zero chance of that being enforced in the UK on fines incurred in France, for instance.
If I were living in the UK and received a fine letter from France - it would go straight in the bin!
Cheers
