Running lights seems to reduce crashes by about 5-10%, and crashes consume a lot of energy. Depending on crash severity there's at a minimum the wasted time for all involved parties and frequently the necessity for repairs (including the production of replacement parts, paint etc), and at the high end the involvement of emergency personnel and their vehicles, hospital beds, doctors, the production of entire new cars as replacement for totaled ones, etc.

I'm not so sure that running lights isn't a net positive, especially with the introduction of LED lights.

On the other hand, crashes also kill people who will then stop be using any energy.

Even LED DLRs?

Next: internal combustion engines doing more heat than torque.

That's a feature in winter. Portable propane heaters for cars are a thing. I think they'll sell a lot for EV cars.

I don’t know. It’s not a thing in Norway and we have plenty of gaz, electric cars, and cold weather.
