...coolant to warm enough to evaporate the moisture...
Where I come from, we just scrape off enough ice to see where you're going, and crack a window to keep it dry enough the interior doesn't freeze. But, hey, if you know how to leave early enough to get to places on time in a warm cabin, more power to you 😉
Or, you know, wake up at the same literal time, no matter what the clock says. Listen to your circadian rhythms, not some number on the wall. The time shift doesn't magically give people an extra hour. That's all marketing. DST stands for Daylight Stealing Time, as far as I'm concerned.
Disclaimer: I'm a night owl; I could care less for waking up early.
