All of these statistics are too generalised to be useful.

People who fly in planes are generally not flying from every conceivable location on the globe to every other one in an even distribution and randomly using every type of plane available on every carrier. Neither are those driving cars driving from every possible destination to every other in every kind of vehicle etc.

Compare someone exclusively flying back and forth between one wealthy first world country to another on a Dreamliner run vs someone driving an 80's Ford Pinto regularly across treacherous mountain passes in the Andes.

Or the converse (use your imagination).

An important and useful statistic is that one particular, new model of aircraft is tremendously crashy considering the amount of time it's been in service.

It makes sense to avoid travelling on that aircraft, until it can be proven to have a flight-miles/crash ratio more in line with other models. (Which may take a number of years, or decades, especially if people are avoiding it...)

What you say is true but coarse statistics doesn't reflect actual situation. You would have to compare 737 MAX deaths per mile to OP car deaths per mile. Maybe taking into account that hopefully OP doesn't speed, drink, text, watch harry potter... Don't know if deaths includes pedestrian or bikes killed by cars, could be irrelevant if you only compare your odds to be alive after journey. I'd also expect a recent car with good safety to have a lower rate than average and maybe 737 MAX higher than average?
