> France has year round DST and an hour on top during summer since 1940 and far less car accidents than the USA both in the morning and in the evening.
In 2019, the European Sleep Research Society (ESRS), the European Biological Rhythms Society (EBRS), and the Society for Research on Biological Rhythms (SRBR) wrote a joint statement to the European Commission advocating for permanent establishment of a more natural time.

This would mean France and Spain being in UTC/GMT, and (most of) Portugal being in UTC-1.
Actually, the document only argues for permanent CET and ending DST. It does not mention change of time zones.
The logic would be sound however. Social Jetlag is real. I for one loath DST and switching back to CET noticably improves my sleep and overall well being.
