Once a major stock holder starts selling his stock like crazy, that stock will nosedive. See Elon "I'll be the last one to sell tesla stock!" Musk dumping tesla stock and check it's current value.

And governments should not ask not to buy SUV's, they should ban SUV's. Yes, ban. They are horrible for the environment, horrible for safety of the driver, horrible for the safety of others, horrible in every aspect and they only exist because car manufacturers want to sell more so they told people they look cool.

Start taxing the crap out of cars, all short distance travel (< 5 - 10 kms) should be by bike, with Electrical the engine support in mountainous areas.we use 2 tonnes of steel and plastics to mostly move single 50-100 kgs persons around. That. Is. Insane. It's unsustainable. Redesign American cities (American being the continent here, not just the country) to no long have these horrible suburbs, make all cities human Centric, not car centric. People should be able to walk to 50% of local stores and cycle to 95% of stores. It makes for wonderful safe cities to live in (see every single city, tiny and large in the Netherlands), makes people healthier due to more exercise, makes healthier air (no car pollution) bad lowers CO2 output by a literal fucktonne.

This would make everything better, which is why it not only will never happen, politicians will beber talk about it because big oil, big car and big whatever the fuck need more bigger cars polluting more because WE WANT MONEY AND POWER.

The world is fucked, sorry.
