RV seat belt safety

Supports my posts throughout the years. With no testing on seatbelts in an RV it seems foolish to extrapolate data from a car to a motorhome. Is a child or an adult safer or at greater risk with a lap belt sitting sideways? People seem to "make themselves crazy" securing their children when they may be compounding a problem. Restraint is probably good, but think about the physics of motion. As for the horrible scary pictures...how about traveling at a reasonable speed. Maintaining the tires. There will always be accidents, plane crashes, tornados, falling trees, drunk drivers, whatever. Just be careful out there, and Happy Trails. JMHO
