So, <<Classical Latin was spoken in Latium>>, <<Tuscany spoke Etruscan>> and
<<Classical Latin in Etruria segued into Tuscan>>.  So somewhere along the
line "Tuscany" spoke Etruscan, spoke Latin and spoke Tuscan.  None of this
answers my question.

I'll ask again.  How do you know that a recognizable Tuscan wasn't being
spoken in Tuscany at the same time Classical Latin was being spoken in Rome?
Do you have any real evidence either way?
