Are they wrong to buy a car that is likely to kill the other person if they’re not driving an SUV? And sure, if they’re driving propane vehicles, or LPG vehicles, or eco-friendly vehicles, then their impact on the environment won’t be so large (although very few people have vehicles like that atm).
Any car can kill a person. Why is their car wrong and yours right? Why is your small car “the standard”
Also, you can convert any car to LPG. Just ask all the Arozona people here. There are hundred of large SUVs (suburbans) on the road there which run on LPG, you can tell them by their blue license plates. Are those vehicals ok? Is it the size or the fuel?
I don’t know about the amount of pollution produced by airplanes, so I can’t comment on that…
Aircraft use a high octane diesel fuel. They polute at a just like cars, they burn fossile fuel only on a larger multi engine scale.
