Computers inexplicably don't do what you want them to do all the time, though. Modern cars, by contrast, are incredibly reliable even with extremely insufficient maintenance.
I beg to differ: my Mazda MX-5 has a lane departure warning system that flatly gets it wrong all the time. My prior car, a Scion iA, mis-triggered the "smart city breaking" on the freeway and nearly caused an accident. The infotainment system fails bluetooth connections inexplicably, and flatly refuses at accept CarPlay or Android Auto connections periodically. And I keep my cars clean and current with maintenance.
