&gt; it&#x27;s more risky to drive back home after the weekend than to recreational cave dive, especially with dive fatigue!<p>I think that&#x27;s the same issue with risk assessment and mixing up probability and impact: A problem when driving home is not a 100% certain death sentence, and it is not something you could not mitigate. You can drive slower, try to avoid dangerous streets etc. And even in the event of an accident you have systems that might save you (airbag etc).
