Although I had be working for a SmartHome platform project in Samsung Electronics, I am more prefer to see the outcome of SmartCar in a short future.
Unlike the smarthome scenario, the car‘s value chain is usually controlled by specific companies, such as Mercedes-Benz and GM. The car manufactures usually control the whole ecosystem, from design, manufacture to build and sales. In the contrast, in the smarthome, there are many household appliances which are provided by different vendors, such as hue lights, samsung refrigerator, Google thermostat and HVAC system. These vendors usually have their own standards. So it‘s difficult to implement interoperability among these devices.
But just as I told in the previous post, smarthome is not just a house within interconnected devices, it should serve a transparent, easy to use and unobtrusive service to the customer. The smarthome service needs to be able to gather information from the network of sensors, review and analyse the data, exploits contextual and situational information from the other devices, make some decision and finally do some actions without human intervention in this loop cycle. That is what we call "smart". So we can see, for smarthome, the barrier is more difficult than that of smartcar.
Besides that, during a long period, car did not change a lot, especially in the appearance, always four tires and the car body. But to the smarthome, there are more and more new different household appliances which did not appear just a few years ago. They also add the complexity for smartHome implementation
In my personal opinion, in a short future, Smartcar will come to our life earlier than smartHome
