Yeah, that would be more informative. But we still need to know about the baseline rates. Trucks are very big, so dangerous to other drivers, and there's a lot of miles driven. On the other hand, there's industry capital to potentially finance safety upgrades, and they're driven by professionals. I'd like to see a more nuanced discussion of what the acceptable risk is, given all those factors.
I'd like to see a comparison of accidents, (or better, deaths), per million miles of personal vehicles vs. trucks. I'm pretty sure trucks will come out as causing fewer accidents/deaths. I actually did the math for the 2009 - 2013 thing, and truck tonnage increased by 21.75%, so a 17% increase in accidents means that trucks got safer over that time.
Possibly true but irrelevant. You could go a trillion miles per fatality, but only the total fatalities matter, perhaps as a percentage of all road fatalities.
