If you are paying attention to your driving
That's the big if. Thing is, cars are driven by people and people can be error prone. Yes even the people that swear they aren't. It's the reason companies have entire HSE/HES divisions.
I like the newer safety features on my car. They're just another layer of safety that can help. I don't use them as a crutch because at the end of the day I'm the one driving. But shit happens sometimes.
My grandfather never wanted AC on his cars either but I sure wouldn't go without. Times change.
