We have all experienced some form of technology security issue from a simple virus to a “denial of service” attack where a system is overloaded on purpose to the point it fails. I wrote an article about technology security earlier this year. In most instances, the issue turns out to be more of an annoyance than a critical and life threatening event. Unfortunately that cannot be said of new cars - especially autonomous ones that create and collect huge amounts of data. With today’s Big Data processing systems it is possible to combine data from vehicles, phones and other devices to be able to see what a human is doing.
