The one I’m thinking on the freeway was a bombardier jet. Granted that’s one anecdotal experience and I have no idea of the stats. So I’m not disputing that it is uncommon.You are talking small single engine Cessna type planes or even smaller. Not a LearJet type craft.
There is a huge difference from a single engine piston Cessna, and a private jet class aircraft.
Saying this happens regularly or often is a major exaggeration.
But I hear of non-passenger crashes with some regularity vs a commercial crash which is exceedingly rare.
