Most accidents happen close to home because most driving happens close to home it says nothing of the risk of road trips - I expect better from HN commenters.
The data doesn’t support the claim that the vast majority of accidents on a per mile basis occur while driving close to home rather than on road trips. The DOT also appears to have published on the side of “replacing air travel with driving will result in an increase of fatalities,” [1] so you’re not even right about your other claim.
“It is known” is not a good basis of argumentation.
