I don't disagree with you but I don't think deaths per mile is a good way to compare modes of transportation. The car/truck numbers include intra-city miles driven for a start. If you can narrow it down to accidents on interstates I think it'd be better.

My guess is that it wouldn't matter much, since accidents at intra-city speeds are rarely fatal.

Accidents on country roads are often fatal though, so maybe that is where the difference would come from (and country driving is not an alternative to flying commercial).

>In 2014, the most recent year for which vehicle miles traveled data are available, the rate of crash deaths per 100 million miles traveled was 2.4 times higher in rural areas than in urban areas (1.81 in rural areas compared with 0.74 in urban areas).

So you're right, country driving is more dangerous than urban driving, but both are far more dangerous than flying on a per-mile basis.

I would disagree, as I'm assuming those deaths include pedestrians, who are rarely present in inter-city travel.
