Cars are getting increasingly cooler, with many new bells and whistles like cruise control and hands-free parallel parking added on year by year. But this also means that cars are increasingly reliant on onboard computers which in turn leads to the possibility of hackers finding their way into your car and having it do whatever they want it to. And although it might sound like the plot of a terrible romantic comedy, think about this: could a hacker hack their way into your heart? Possibly, as many newer pacemakers are set to a wifi signal. It's a scary prospect, but one that we have to face.
