So you admit to making decisions or taking lines of thought based sometimes of having no actual evidence.
you have filled you're own criterion for having faith.
No why would you think that?
I have evidence that bridges are designed and tested ( I even know an engineer that does this).
I know that no system is perfect, so there will be an element of risk, and I judge the risk to be small.
No faith is required.
You can believe ANYTHING by faith, so by definition this cannot be a reliable path to truth.
Do you care if your beliefs are true?
If so, you must NEVER use faith.
