In a lot of cases, yes. But pickup trucks actually are useful. At work, we couldn't get anything done if we didn't have our crew trucks. My first job, I worked for private residential contractors (home remodelling, additions, etc)... gotta have a pickup truck if you want to actually get work done. A couple weeks ago, I saw a Ford Super Duty pickup truck hauling a big gooseneck trailer with a small excavator and a bulldozer on it. Yes, an excavator AND a bulldozer.
And not to forget, I've used my pickup truck to move all kinds of things that would've been impossible with any other kind of vehicle. Couches, computer desks, large recliners, big boxes full of clothes, console televisions, exercise equipment, home theater centers, and any number of other big things.
But I do agree. There are too many people that have pickup trucks just to have pickup trucks. Just today, I saw an old woman (probably in her late 70s or so) driving a crew cab long-bed Chevrolet 2500 HD. Now, what the hell do you think she's going to do with that?
