text: How safe are these cars? They are safe until they have a technology mishap or faailure. You can not always trust technology. Any question of these cars could be asked. But what if they can't be proven? For instance if your car doesn't warn you of danger, road construction, or any detours and you're asleep. But your car didn't warn you. How's that your fault? That's the thing they will tell you that you were "driving" so it was your fault.
