One can, and many do, die in car accidents due to their own mistakes. We take measures to mitigate that risk, ie wear seat belts. Bad things happen, it makes sense to be prepared. There may be those that would use technology as a crutch, but others of us use it as an added layer of safety. It gives one more options in critical situations. With an aviation background, I know that options and layers of safety are of utmost importance. I still put in just as much prep as I ever have (actually, even more now thanks to the fantastic features of google earth and being able to do a 'virtual reality' tour of our target areas), but carrying a little device that weighs mere ounces and could save my life or that of someone else is a no-brainer. It's not about preventing the inevitable. It's about mitigating risk, ie 'putting on a seatbelt'.
