I haven't had one fail in a while, but I also primarily drive newer cars now. When I was kid and young adult it happened.You're describing a very obscure and rare event, compared to a certain and every day detractor of the vehicle not warming quickly. It's all in your risk assessment and if you'd rather the former, just yank the T-stat.
I'm sure that it could be engineered to default open and close under conditional input, but that would add cost and complexity to a system that they've determined to be low risk for what you're describing. It's been a very long time since I've had a Tstat hang up or even heard of guys having it foul up.
I am not asking for a thermostat that starts open. I think you fundamentally misunderstood what I was saying and the other poster as demonstrated by this reply. If failure is obscure and rare then how would a failure mode that resulted in the tstat failing open result in everyday slow warming of the vehicle. I am ONLY complaining about the failure mode not how it operates. I am not saying the thermostat should operate in reverse, only that in that rare and obscure time it fails that it fails open.
