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. Are these parts not part of the car?
