5 Photo essay on the history of cars and your privacy within them!?

For this photo essay I am going to be using Lexus © cars and SUV's as my example.
With technology advancing at a rapid rate so is the amount of technology used in cars. Lexus, and many other vehicles are coming equipped with a driver monitoring system that "sees" what you are doing while you are driving.
They claim that this feature is to prevent you from crashing if you, for example, fall asleep at the wheel and begin to drift one way or another. They also monitor the road in front of the vehicle. If your head it not facing forward, determined by the infra-red camera mounted on the steering wheel, it will sound a warning making you focus on the road on front of you. Below is a photo of the camera and infra-red camera that is watching you.

Along with a infra-red camera watching your every move most cars on the road are now equipped with OnStar service's. OnStar systems also monitor your car or SUV and contact emergency services in case of an accident. As most people are aware, if your car has OnStar it also has a microphone somewhere in the vehicle. Is this microphone being used to monitor conversations you are having in your car? It is another possible way they are using advancements in technology to "Protect us from harm".

Lets not forget about one feature that seems all to helpful when we are lost on the road; GPS. GPS has been a life saver for me while I am going on road trips to an unfamiliar area. I always was thinking about how the GPS knew exactly where i was, within feet of my actual physical location. When I first realized this, I had always wondered who was tracking me, that is if anyone actually was. 

Why cant cars be simple like in the past? I like my very basic Audi, it has the things I need to get by, without all the added "luxuries" that could be used to invade my privacy. Simple, but not ugly. Just the way I like it.

Technology is advancing at a very rapid rate, and soon enough cars will be driving, or flying, themselves while we just go along for the ride. When that day comes, we will be monitored the entire time we are in a vehicle, without a doubt. The future scares me as I am a very private person. I like my personal life to remain my personal life.  Even in this day and age I am unsure as to if the conversations held within a car actually remain private. What does the future hold when it comes to privacy within out personal vehicle? The world may never know, until that day comes.
