Reducing your meat consumption is likely the most effective way of lowering your personal climate ‘footprint’.

You don’t even have to go fully vegan. Use 20%, 30% or 50% less meat and you’re already doing a lot.

Also look up climate impact of different types of food (and where it comes from), and use that to prioritize. Chicken, fish and pork are up to 10 times less impactful than beef.

This article actually covers a specific kind of gas stations in Germany along the Autobahn, that are centrally regulated and are, exactly as you say, also truck stops with lots of amenities and space.

I just did a trip from Copenhagen to the south of France (1900 km) in an EV. The biggest issue for our trip was that Tesla’s superchargers were half the price of the other networks, but were never at the typical rest stops that also have bathrooms, 24 hour shops, etc. So we opted for the cheap charging over amenities.
