When driving a vehicle keep an eye open for horizontal lines off BOTH sides of the road. If one sees vertical lines it's either foliage or it's man made. If it's a horizontal line then it's either a cross fence(wooden) or it's a living creature. I've had so many close calls with creature/vehicle collisions ESPECIALLY @ dusk/dawn & also foggy weather conditions that I have adapted to a modified defensive driving mentality, like 5/10 mph under the speed limit in weather that impedes my vision, & also during night time driving on the back roads & freeways/highways. I also beep my horn about every 15 seconds or so which will anchor most 'wild' life in their tracks. I have developed a very keen eye for the off road horizontal lines if for nothing else front end & windshield/radiator repair$! The vid below illustrates what can happen so freaking fast even on a bright sunny afternoon with unlimited visibility on a reasonably flat landscape no less!
