This is a “pet peeve” (I hate that expression) of mine. IMO, people are usually not properly trained to operate the things they buy.
A case in point: Several years ago, the Suzuki “Samurai” was called “unsafe” because they roll over. DUH! Off-road-type vehicles were designed to go off-road! The higher ground clearance raises the CG, making them less stable along their longitudinal axis. Hence, you have to slow down when taking a corner. Anyone who’d ever driven a Jeep-type vehicle before the SUV boom hit knew that. (Take a look at the older “Jeeps” vs. the newer ones. The newer ones’ wheels extend a bit outside of the body. The older ones’ wheels generally were flush or inset from the body. The wider wheels improve stability, but limit the narrowness of the trails that can be used.)
When I bought a '48 Willy’s CJ-2A back when I was a “kid” (in the early 80s), a friend advised me of the need to go slow around corners. He also taught me the basics of off-road use. The people who see a commercial and then go out to duplicate the feat need to understand that there are certain operating parameters designed into the machine. The reason the “professional drivers” can do it and they can’t is because the professional driver knows what he’s doing.
Every day, I see people riding in their cars on the freeway. They’re only riding; not driving. They simply happen to be in the left seat. “Left-seat passengers”, I call them. You have to pay attention while you’re driving, especially off-road. When you’re off-road you can’t just be Mr. Toad and take a wild ride. You have to look ahead, assess the trail (you do stay on the trail, “treading lightly”, as it were, don’t you?), plan your reaction to what will happen next, and maintain control of the vehicle.
Whether you’re on the road or off, don’t be distracted. Putting on makeup, shaving, reading the paper, talking on the phone, listening to the radio, changing a CD, eating breakfast, etc. are less important than not hitting the car in front of you. If you need to take evasive action, drop the Super Star with Cheese on the floor. You can clean it up later a lot more cheaply than you can fix bent sheet metal. (OARN: I was taking the flight test for my helicopter license. The examiner was talking and I could see that operating the machine needed my attention. I told him, “Stand by.” He told me later that telling him to shut up and giving my attention to flying the aircraft displayed good judgement.)
Okay. End of rant. They put the disclaimer on the commercials so people who don’t know any better won’t go out and try to drive like a professional without first getting the training or experience.
