Yea this looks misleading as fuck. Weight graph starts at 3000lbs too. Also no mention of the cars polluting the nearby environment a lot less despite getting heavier. And why measure acceleration instead of measuring brake distance, or pedestrian survivability, or crashes per million miles etc.
“A lot less” is something I’d like to have a source for, especially as the switch to SUVs and trucks is done to a large part to evade the much stricter emission norms for officially classified “cars”. Emissions could be a lot lower if the SUV loophole for many of the car norms had not been invented.
i think this is about toxic gases emissions vs CO2 emissions. while CO2 emissions have probably gone up somewhat (my guesstimate is +30% since 1970), the toxic gas emissions have almost completely gone to zero. there was a whole lot more toxic gases around in the 20th century industry and machinery, you had to cough constantly, we just don’t remember it because it’s comparatively clean now.
Toxic emissions have absolutely not gone down to zero. High respiration activities next to a highway still get you a solid dose of toxic stuff. Yes, it would be much worse with 1970s vehicles but it would be much better if the majority of vehicles sold today would not be able to use the regulatory SUV/truck loophole to be able to pollute more. This loophole is not just about CO2.
I witnessed myself what a huge impact on air quality it had on a street to see heavy two lane traffic gone and that had nothing to do with CO2 and it was even without that loophole you have in the US.

yeah axes should start at zero.
