We're not talking about what I'm worried about, we're talking about what the FAA and other similar airplane licensing bodies will permit, and they are not allowing the MAX to fly for any purpose right now (save the one-time ferry flight to a parking spot until the problems are fixed). These licensing bodies only do airplanes, not cars, and so the safety of cars isn't relevant to them. But yes, on a personal level, I too find it shocking how >37k people are killed in motor vehicle crashes every year, with countless more injured, and yet we're doing so little about it. There's clearly a lot of low-hanging fruit there.
