These two clips from Dashcam Owners Australia prove that it's not enough to just pay attention to your own driving — you have to pay attention to what everyone else is doing, too. First up, a car crossed an intersection at the wrong time and hit another car head-on. The driver claimed to have been blinded by the sun, which is some excuse!
Next, while driving on the highway, one driver tried threading the needle while switching lanes, but ended up side-swiping two cars before speeding off. The accident is still under investigation, but thankfully there was a dashcam to capture the whole thing.
