Electric cars.
While I think it's a novel idea to power your car with the limitless energy of the sun or whatever, it doesn't work like that in reality. Where I live, we barely get 8 hours of daylight for 3 months of the year, which is definitely not ideal to power your home and keep the heater running when it's cold outside. That extra electricity you would need to charge your car would have to come from the power grid, which isn't going to be renewable if you live in the US. Just to give you an idea, slightly less than 23% of the power in the US is "sustainable;" 13% from renewables and 10% from nuclear. Natural gas powers almost 32% of what we need, but when you consider that natural gas is used a lot for public transportation, like buses, your Tesla with the license plate n0emm1sn is pretty fucking cringe. It's more likely than not that your "clean energy" mobile is ran off the same shit I dump in my Ford 4 banger. I wish I could say I'm shitposting about the license plate thing, but I've seen at least a dozen different Teslas with different owners driving license plates with a variation of being clean energy or whatever.
In general Elon Musk Stans collectively have taken all of the chromosomes for themselves, but I can't handle seeing the delusion in real life. There's something in me that breaks. Like I expect to see an Elon Musk Stan arguing about why TSLA isn't a bubble and how daddy Elon is saving the world, but when you see something so into the trickery that they buy a car and make the dogma their license plate, there's just something extra to it. I dunno. I never expect to see the Internet intersect with real life.
