I've seen a wheeler change from a 5 point "latched all the time" to a "lap belt will be just fine" after some heavy drinking. Ever see someone get knocked out on their roll bar tubing, cause they were just wearing their lap belt? It's scary seeing a vehicle driving itself, with no way to stop it. It's not just the lives of the people inside the rig that are at risk. What gets me the most is,how much time and money that has been put into one of these high end buggies to make it as safe as possible. High dollar suspension seats, harnesses mounted in just the right way, the right size tubing, with the right amount of triangulation, the right distance away from your head. All for what? Nothing! I see it as monkey see monkey do. For a veteran, who has been wheeling for 20 years, proly will be fine driving up a easy trail with his lap belt. So the novice figures they can do the same.
Be an example. A good one.
