Hmmm. If the car decided, before your trip started, that it's too dangerous for anyone to drive where you want to go because of possible weather and environmental conditions mid-route, would that be useful or enraging?

I imagine a bit of both. Getting caught in a snow storm is a pretty horrible experience, and I would gladly stay home knowing I would have otherwise ended up in one. But at the same time the forecasting isn't all that great, so often the storms don't amount to anything, and you would have been perfectly fine to be out there. Sometimes the storms even come up without any warning (most of the snow we get – especially that which causes driving issues – is from the lake, not the clouds). Having to essentially hibernate in the winter because the car is always erring on the side of caution could become pretty enraging.
