I hate this kind of "do gooder" tech.
It's one more thing that will be imposed on us for the greater good making our lives a tiny bit more complicated and a bit more expensive.
This thing will break and will have to be repaired.
It WILL have bugs that warns you for nothing adding a bit more stress to lives that don't need more.
Now if you ask me, it's probably viable commercially and I expect to see this kind of thing in new cars in the next 5 years.
I'm surprised it's not in standard already, but maybe it's a too processor intensive for a cheap controller.
