His truck is an environmental abomination, and almost certainly not as safe as a more modern vehicle, not to mention the hundreds of hours (thousands?) he's had to pour into understanding his vehicle and performing his own maintenance.

Diesel actually is a more efficient engine than gas. It produces less CO2 than gas too per mile. The only thing is the visible black smoke that comes out of my tailpipe every time I pass Tesla. JK, my other car is a Model 3. I just YouTube all my questions.
diesel might be a bit more efficient, but produces more nitrogen dioxide (and other oxides) which are harmful to humans and the environment, which is why they are being banned in some parts of europe.
