Ah, the minimum effort approach to patting yourself on the back. Note that the least fuel intensive act is to not ride the train or the Hummer, but that would actually be disruptive. The correct answer was to use an electric car powered by solar (because the current zeitgeist doesn’t care about manufacturing). Thanks for playing though, you’ve been cancelled.
Lol it’s not like building a solar car has no ecological cost, the amount of times you’d need to ride the train to come close to equaling the environmental cost of buying an electric car alone is immense - probably long enough for Caltrain to become electrified and powered by renewables, but idk, Bay Area government always surprises me with its incompetence.
