...in Chicago ... pre-heating the car is a must 3 months of the year.
I don't believe you've lived anywhere cold for very long. Cold places existed long before remote start. The car warms up while you finish shoveling and brushing off the car. You're warm from shoveling, and the car is ready to go. If it's just cold and you're late to whatever, you sit your shivering ass down behind the wheel and drive away anyways...
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.
