The last few times we visited Europe, the car rental places basically defaulted to either electric or automatics, but all three options were virtually the same price, or the manual is only a few Euros cheaper.
This last time we went to Spain, picked a manual, got to pickup where they told us they didn't have a manual and would we mind a free upgrade. Sure! They offered us an electric. We needed to do a lot of driving so we asked if they had something else, we ended up with a Toyota crossover Hybrid (CR-Z maybe) which was a CVT.
Merp.
I don't know the stats but it seems even Europe is starting to shed manuals. I don't know if its the popularity of electrics that has finally busted through or some other cause.
Another anecdote, we sometimes ended up a taking taxis while in Spain and Portugal, not a manual in sight, which was notable enough that I remembered it.
