Big differences are evident on the Frankfurt show floor today between bank-watching financial hacks and car execs. The money men seem full of foreboding, concerned that Europe's central currency is about to implode, with all the uncertainties this will bring; the car men are full of predictions that annual world demand cars will rise from today's mere 70 million to 100 million plus around 2020, when customers in India and China truly get going.
