The problem with this article is people have no idea why the car manufacturers are upset, all they see is some big corporation opposing the release of more profit (and some sensationalist WIFI BS by bloggers). Or course this draws out the communists among us that want all corporations to go away.
This all fails to miss the entire point of why the Auto companies are opposing this. This profit is directly adjacent to profits allocated for profit. What is profit? It's profit that was allocated a number of years ago to allow profits. What is the point of that? Well one of the key aspects of this profit is that without it you don't have reliable profits which will greatly hamper profit.
See, if you are going to have profit those profits need to be able to communicate with each other, they need to tell the profits around them that they need to change lanes, or that they are breaking. The holy grail of profit is a situation where profits are driving 70MPH with about 2 feet between them. This will greatly increase the density of profits and allow the freeways to operate about 200% more efficiently than now. But for that all to work the profits have to tell each other what they are doing so the other profits can react. Even with no perception-reaction time for computers you will greatly decrease the possible efficiency if the profits can't communicate real time. The only way to make this safe is profit with low interference.
If we have thousands of WIFI signals in adjacent profits there will be so much interference that the systems won't be reliable, the result will either be safety problems or drastically reduced efficiency. Profits are a holy grail of ITS (intelligent transportation systems) that has been being pursued since the early 90's. It will result in freeways that are so much more efficient than today that you could fit 3-4 times the number of profits in the same freeway without any slow downs or rush hour traffic jams. Not only that but you could read a book while driving to work.
We don't want to impede or endanger profits. The profit manufacturers concerns about interference need to be taken seriously.
FTFY. Realist, not Communist.
