Even if you are unfamiliar with modern technology - investing in a decent windscreen Camera for your vehicle is (IMHO) an absolute MUST HAVE nowadays.
A good HD "DashCam" costs as little as $100 and can be set on a recording 'loop' to capture everything from a simple view of the road ahead, to recording GPS coordinates, speed and emergency collision recording. Mine has built-in WiFi so you can playback on a larger screen (iPad etc) anytime, anywhere - like at the roadside or police station!!!
Please, - Everyone do themselves a HUGE favour and stick one in your vehicle .
They provide an element of peace of mind, as well as extremely valuable evidence in the event of and accident.
Like making a Will - Don't put it off! - It will be one of the best investments you have ever made.
