Unfortunately, one doesn&#x27;t need to own or even be driving a car to still be injured or killed by one. There are many aspects of cave diving that one can influence (checking and servicing equipment, having redundancies) to be safer, as well as many thing about driving and cars that one can&#x27;t influence (who else is driving around you, the state of mind of who&#x27;s driving the car&#x2F;bus you&#x27;re in)<p>I think the real difference is not necessarily how safe or dangerous one or the other is, but one is a risk that is practically necessary to function in society while the other is not.
