Driving to the gym early this morning before any hint of sun was up. The road is a simple two lane road with no shoulder. and it's on the edge of town so no street lights. Some guy was walking along the side of the road (with the flow of traffic) in dark blue jeans and a black jacket. I absolutely did not see him and the Genesis applied the brakes heavily suddenly such that it shocked me and I wondered what the hell was going on. I did not see him until as I was going by. I don't know what the outcome would have been had the car not alerted me, but honestly I don't even want to think about it.
