In the good old days of driving, we needed to make sure the mechanical things worked: Things like the engine, of course, the steering and the brakes. We were in charge of driving the car.  Now, for better and for worse, technologies are moving in and taking over. Sensors, cameras, on-board computers, software. Those powerful technologies are mostly invisible to the naked eye. They give us directions and infotainment; they help to avoid accidents. The more advanced technologies can now deliver us from Point A to Point B without human intervention. That's quite amazing when you think about it. And more than a little bit scary. How do we know that the sophisticated hardware and software will operate safely every time we get into the car? The reality is that there is no such thing as a perfect system, at least not yet. But there are ways to minimize our risks. That's where QNX comes in. The company, based in Ottawa, Canada, delivers real-time operating systems for safety critical applications.   As COO John Wall says, the modern car is becoming a robot on wheels. How can we know for sure that our robot remains our best friend, always looking out for our safety and security? John Wall has answers, today, on the Driving With Dunne podcast.
