The former Zombie Ram, before going out in a blaze of glory like a Shofixti Scout, actually had 12 solar panels. Indeed, partially why I had the gas engine was for the alternator for the reason you just stated, though I start in spring. It seems to rain/cloud in this region virtually every day.
For whatever reason, they seem to love targetting my gas tank and ignore everything else… And I rarely go above 48 kph in cities, maybe 80 outside.
And… well, I’ve yet to hit a mine thanks to perception, so for all we know, you just didn’t let the RNG see if he wanted to mess with you or not!
