For node/306427996, the value "ref:FR:prix-carburants": "35650001" and associated infos for the stations are wrong. There are no stations in Le Rheu with this id and adress (rue de Rennes). The "ref:FR:prix-carburants" tag and fuel amenity should go to way/123784431 as the adress and the coordinates from source prix-carburants matches (rue de Mahomat)

way/173972955 comporte une clé maxspeed à 50 et une clé invalide (selon les conventions du wiki) maxspeed_1 à 70

Fix speedlimit value on above relation way/497464075
It's more than the speed of sound (1022mph) except if there is a jet allowed around :) , it seems wrong.

relation/144876739 just below has a speedlimit to 900. Quite impossible. Not sure I can correct to 90 as speed limit on the Flanders side is likely 70 according to osm.wiki/OSM_tags_for_routing/Maxspeed#Motorcar (PS: foreigner so not well acquainted with local rules)
