Here is my take on the subject ( as if anybody cares ).
DRL = Daytime Running lights have been mandatory in Canada since about 1988.
So far, it is estimated by the Insurance Bureau of Canada, they have reduced accident rates by 20 - 25%.
Most states in the US that I've travelled in, call for " Headlights ON when the w.wipers are on " anyway.
Many people here thought it was a stupid idea when first introduded........today, nobody would give up the same feature.
On the fahrenheit/celsius conversion, well, you'll have to drag your government out of the " dark ages " & get them to switch to the metric system.
