I strongly endorse providing detailed critical feedback about personal risks that people are taking. Unfortunately, there's no way to predict all the possible ways that someone can put themselves in danger with complex equipment in an unknown environment. A million years ago, I tried to list some basic equipment to help avoid the most obvious waysmost obvious ways to auto-Darwinate.
None of those would help another situation (which I can't locate quickly) where a user was wondering how to monitor their fuel pressure and wanted to locate the gauge inside the cabin. As this was going to be a gauge fed by live fuel, not a sender, I recommended that they not run the risk of creating a mixture of pressurized fuel, people and oxygen inside their car....
This is one of the areas where expertise and hard-learned lessons can really help people. Keep an eye out and chime in: there's a real chance that you could save lives here.
