One could call this an evidence, really. I guess it is possible, then.
:-)
Did this happen only during those extremely cold periods you experinced,
I mean, do you think one could see this in Finland, with typical
temperature about -15 degrees (Celsius)?

Perhaps something to do with the total lack of driving licences at that
time...

Above, you already gave very strong evidence for fast enough ice crystal
formation in industrial plumes. Here the situation is different,
however. First, there already exists water droplets, thus there is no need
for
growth. Second, Freezing and deposition are two different processes.
Thus, I would say your own observational evidence is much more solid.
