I don't own a car, but I rent cars on vacation and use Silver Car and City Car Share when I need one. Since I end up getting whatever car is available, I have to learn a new UI every time I drive. I also end up frustrated with how complex and distracting car UIs are. Even when I tinkered with Tesla's UI, which has gotten a lot of praise for being a huge step up from existing car UIs, I was frustrated by how much attention I needed to give to small tasks like changing the volume.
While I still think voice is the ultimate UI for cars, this concept presents a great easy-to-use interface that takes a lot of thinking and finding out of existing car uis. I’d love to see this concept paired with a second display in front of the steering wheel so the driver doesn’t have to look over. Some sort of gesture key to replace the empty black screen would help learnability too (as well as present a reminder for how to find less commonly used controls). It could disappear when the user begins to interact with the screen. Software like this could be open and plug into lots of different cars (kind of like Android does with phones) so that people aren't learning new UIs for every new car.
