How does google maps know what the traffic is like? Where does it get the data? I find that fascinating. Are there sensors in our highways that send information to a server somewhere? Or is a gathering information from our cell phones? Wow, I have actually never thought about this before. Some very smart people have put this together. I just can't wrap my head around all the data that would be necessary to make it work. I can't even imagine where you would get the data. How about all the programming that needs to be done in order for it to function the way it does. That is just mind boggling me.
What do you think?
