Yesterday we had to drive through a very heavy rainstorm throught Jacksonville Arkansas, it had be raining hard for over 3 hours, dropping an average of 3" per hours. There was alot of standing water on the interstate & in areas water was flowing across the interstate, the car in front of me got swept onto the hard shoulder. Both lanes were packed with heavy traffic, my front wheels started to move/hydroplane, but the the rear wheel got traction & I was able to miss the car infront of me and stay on the interstate. Man it scared the crap out of me. But I believe it was the 4 x 4 systen & stability control systems that saved our butts that day. The Ridgeline is a great little truck. I am now a dedicated Honda owner. Also the inside of my truck stayed dry.
