fooey on automobile history

Went haring off to find out how automobile side windows opened at the turn of the century . . . to discover that they didn't have side windows, or any sufficient protection tio drive around in winter time, until the 20s, which is kind of too late.

How on earth am I to transport Yanek and the Duke's children around the landscape in the middle of winter then?  They'll freeze if they have to drive in an open car for several hours.  Carriages?  What about the horses?  Didn't they suffer horribly in that cold?
