You don't get out much I'm afraid. Average is 24-48 months for a automobile lease, and 25 percent of all vehicles in the U.S. are currently leased. 43 percent of all vehicles sold in 2018 were SUV's or Pickups. Before you accuse me....my newest vehicle (I have 3 for a family of five) is a 2004, that I bought third hand and has 280,000 miles on it. It runs fine and i get to where I need to go int the winter without any drama.
As far as cultists...Not a one of us here works for NOAA or NASA. None of us are actual climate modeling specialist or meteorologists, yet we go one about it like we understand the science behind it. We act as it was life or death, and any affront to our preconceived notions are like an attack on our belief system. You won't convince anyone to change by attacking them or beating them with facts. Few people respond well to that. Just better off doing yourself a favor and find a community project to repurpose land-fill materials or participate in a river-cleanup project.
The vast majority of people are not likely to actually do anything other than talk about climate change anyways.
Pollution (CO2) output in the USA hasn't effectively risen since 1990, despite a large population increase. China currently more than DOUBLES the U.S.A pollution output, yet people instead argue with someone (likely an anglo) on an anonymous internet forum, watch a documentary, donate 5 bucks, recycle a few bottles, change their lightbulbs and call it "Mission Accomplished". Some might even go so far as to get the proverbial T-shirt made in China by 14 year old kids, in a factory pouring raw waste into the river.
