FWIW, just returned from 2 weeks hols in that France place. Macron has doubled the state discount on petrol to 30c/litre ("up to" according to the retailer choice apparently). Lowest price I paid for E10-95RON was Eu1-36 per litre, that's around £1-25 allowing for the falling £.
There again, they have also capped the electrickery increase to 4%, so the relative costs of running electric vs petrol there are in a somewhat different league to here.
