The chuds driving jacked up pickups aren’t contributing very much to global CO2 emissions actually.
The tendency of individuals to place far more blame on passenger vehicles (of which medium and heavy trucks constitute less than 1/4th in the US- likely far less elsewhere) as a contributor to global warming than they are actually responsible for actually had a name; The Transportation Fallacy.
Exact numbers vary by year and country, but it seems like passenger transportation accounts for about ~7% of global CO2 emissions. To put that in perspective, the same source indicates that we can remove the same amount of CO2 by eliminating food waste as we would by taking every passenger vehicle on earth off the road.
The auto manufacturing lobby wants you to sell your current working vehicle and buy a Tesla or a Prius, even though the carbon debt of manufacturing that vehicle won’t break even with an IC engine for ~300,000 miles. And even when it does break even with your current vehicle, if everyone on earth did the same thing, it would barely dent our global emissions.
They want you to feel satisfied about doing your part in a way that earns them revenue, instead of focusing your energy on things that will cost the energy lobby money but actually have an effect.
Sorry, long rant, but I wish more people realized how convenient of a scapegoat the type of car someone drives is. Yes, a more fuel efficient car is better than a gas guzzler, of course. But that’s such a small part of the problem, yet it gets such a huge amount of the mental energy that people spend trying to reduce personal emissions. Eat less meat, push for nuclear power generation, make sure your home is well insulated and uses efficient appliances, fight for working from home where possible, switch from grass to native plants. Drive less. The chuds rolling coal are idiots, but they’re a very, very small part of the problem. So many better ways to spend our energy.
