I wonder how diesel-engined trucks manage in the low temperatures. Must
be a real problem for them. Maybe they have heated fuel tanks.

I'd always presumed that the cheapness of petrol in the US was the main
reason why diesel-engined cars have never taken off as they have in
places where fuel is much more heavily taxed. Also, I notice that over
here, very few diesel-engined cars have automatic transmission - diesel
and automatic seem to be mutually exclusive.
Yes truck fuel tanks are heated, but if you tried this in a car you
would flatten the battery before starting. Locomotives with both
electric and Hydraulic (an advanced automatic to you) have been around
since trains first started to use diesel engines. Please do try and
keep up.
