It isn't just cars that are getting smarter - go-karts are too, thanks to Nest co-founder Tony Fadell's new venture.
Using the app, they can even bring the car to a stop at the touch of a button.
They can even set a top maximum speed, so that kids will have to demonstrate they're responsible before being allowed to really punch it.
On the inside of the kart itself are a bunch of a collision sensors, which like in a Tesla or other modern cars will bring the vehicle to a stop if it senses it is about to hit something.
It can then even send a notification to a parent's phone, so they can run out and check that everyone is still alive.
Now how about inventing a version for adults, and making it socially acceptable to ride a go-kart to work?
