That's a "want" not a need. And that want, like a lot of wants in the tech world, was bought by making a pretty large attack surface theoretically that seems to have been taken advantage of, in the same way people "want" the internet of things and are surprised at how it is abused too. I think techies need to understand that sometimes, it's better to be cold for five or ten minutes than find out the car's servers are down, or the battery in their fob is dead, or they are in a place where the car can't connect to the net. The high potential cost of convenience is there, even if it is rare.
