Even cars built 5 years ago are lot more energy inefficient than newer vehicles. For example, I drive a 2016 Jeep Compass that get 20 MPG combined (15 city driving and 24 highway driving), whereas a 2022 Jeep Compass gets closer to 25 MPG around town and 35 MPG on the highway. Better fuel economy means less of a strain on the environment due to less of a need to fill up as often.
there has been modest gains in the last 5 years, but nothing spectacular.
the avg mpg has gone from 22 in 1986 to 25.4 today. Not good. That's mainly due to all the selfish, ignorant c**nts in full size pickups and SUVs.
Figuring out a way to convince the sheep, the bros and the karens to think of an Escalade as something to mock(it's a full size Chevy truck with whore makeup on), not something to aspire to would do a lot to push us in the right direction.
Also, cars are super expensive right now and inflation is a problem if you haven't noticed. Subsidizing people in 5 year old cars to buy new ones might not be the best use of tax dollars (and also another way to give money to a group of people who don't need it...what is it with red avs wanting to give free govt money to people who don't need it lately?).
