In the USA, can one depart VFR and then change to IFR and back again?
Here in the UK this is done all the time. But one isn't supposed to do
it in e.g. France because *any* IFR requires an IFR flight plan, and
an IFR clearance.

The last bit should be OK because one can cancel IFR, AFAIK.

Europe's system is not flexible, we are.

Like the US you can file a pop up IFR flight plan if needed, for example if
the weather goes a bit pearshaped and you want to fly in controlled
airspace.

The UK has class A going down to the surface and a special VFR clearance is
available in that airspace. Other class A not at the surface is IFR only
like everywhere else.

Interestingly from FL245 our airspace goes to Class B
