Adding seat belts to a class A?

Your family is safer in whichever vehicle is driven more safely. Probably on the whole, most motorhomes are driven more carefully than most cars, allowing a greater margin for reacting to changing situations and avoiding really bad weather and operation by impaired drivers.

In the event of a crash, I'd much rather be in a modern car than in virtually any RV. There are far fewer things to become missiles in a car, and the structure is usually more crashworthy (and would stand up to a rollover far better). A car also stands a better chance of being able to avoid a crash in the first place by quicker braking or maneuvering. Cars typically also have better crash protection systems like airbags and shoulder belts and active headrests and well-engineered crush structures in front of the passenger cabin.

In some situations, such as multi-vehicle collisions, the additional mass of a motorhome is an advantage. That's about the only inherent advantage over a car that one has in the event of a serious accident.

I used to work traffic with an accident crash investigator. While the safety systems in modern cars are great cars don't have the mass that large vehicles have. The police accident investigator used the "the lug nut" rule. The larger and more lug nuts wins. This has been proven time and time again with thousands upon thousands of accidents over many years. This is pure physics. While larger vehicles are more prone to rollover than are smaller vehicles that issue is offset by the significant additional space between the roof and the occupant. Most modern Class A motorhomes have steel or aluminum structure above the passenger compartment to protect the occupants in the even of a rollover crash. It is important that occupants are restrained in the vehicle as an unrestrained passenger could strike internal structure or be ejected and injured or killed. It is also important that objects inside the coach are secured to avoid having them become missiles and striking passengers. Finally, it is really important to understand that if a large vehicle hits a small vehicle the large vehicle will slow down much more slowly than the small vehicle. If you spend much time on social media you can see some interesting dash cam videos demonstrating this. For me I would much rather have my family inside our motorhome than inside my wife's Nissan Leaf in a crash. Your point about the maneuverability of a car vs a motorhome is warranted and true however that is offset by how they are usually driven. Finally, on my background. I have directed traffic for years on a volunteer basis, I have a Commercial Driver's license with a School Bus and Passenger endorsement, and I have been working in IT for a large commercial heavy truck manufacturer. The biggest problem we have in accidents isn't the truck driver, or passengers being injured it is the people in the vehicles that either the truck or bus hits or hit our vehicles. Occupant protection in our vehicles is really built in due to their size. We are working on ADAS and automation to allow the truck to see a hazard and attempt to avoid it prior to a collision and or reduce the severity of a collision if one occurs. All most all of this work is to reduce the death and injury for the occupants of the other vehicles.
