I think this is a futurist persons painting a sexy picture. In reality, it would be cool if - as we slowly approached a self driving world- the vehicles could relay real time road conditions to the cloud. This of course would enable the vehicle to be aware of upcoming road conditions. It’s not so much that the internet connection is doing the driving but it could aid it. Something simple like potholes. They show up after a rain and get fixed a few weeks later (if you’re lucky). If the car knew there was a pothole ahead and knew to drift to the left portion of the lane to avoid it that would be nice. The vehicle wouldn’t have to do real time jerky swerve reaction because it knew it was coming. Maybe next month a vehicle notices the pothole is gone, the cloud forgets about it. Something like this is the practical use of IoT on the roads.
Certainly not this one simple example in a single device (vehicle). I don’t know where our 3/4 G limits are but I think if you multiply the data transmission by many millions of devices and many millions of reasons to communicate, it’s possible it would put a strain on our present network capacity.
