You are driving and having a discussion with your passenger when your radio joins in and offers a few comments. You cars computer system has been hacked. Now I don’t know if the ability to talk will be possible, but it is possible to listen into a conversation. The hacker can also tell your location using the GPS, disable and apply your brakes, they could also disable the ignition and lock or unlock your doors. I think there are several more apps that will come up as more hacking is done. Think of that 17 year old you have been yelling at to stay off your grass having control of your cars computer systems. He will be the one laughing as you try to unlock your doors to exit your car when you get home. You will notice many of the items that can be hacked are also ones that can be accessed by On Star, don’t know if this a coincidence or not. I am sure the HVAC system will be on this list as will security systems. That 17 year old could possibly turn up the volume and change channels on the radio, remember you are locked in. Rethinking that emergency escape tool you seen advertised earlier.I don’t know how the manufactures plan to update the onboard computer systems but I hope some serious security is part of the plan, but then some other 17 year old geek will beat it. Listen up shops time to hire a geek, don’t wait give them the opportunity to get in on the ground floor. I am not the sharpest tool in the shed but I started when computers were in there infancy, greetings cards have more memory then my first computer, I grew along with them. When I say MS DOS or Windows 95 and you don’t start giggling you don’t know what I am talking about.
