Uh... the "Fatalities by passenger miles" chart in that article says that fatalities per billion passenger miles are 70 times lower for commercial planes vs. buses.

And in fact if you normalize to actually comparable transportation modes, my guess is it's even worse. The overwhelming majority of bus miles are driven on urban transit routes at low speed. You'd want to split out long haul (Greyhound et. al.) buses to compare to aviation, and highway travel is always going to involve more fatalities.

Basically, even knowing that it's probably the most dangerous jetliner in decades, I'd still view a 737 MAX as an extremely safe travel option.
