If a pipe under your kitchen sink is leaky, you don’t need to conduct a months-long study. You don’t need to create a plan to replace your kitchen plumbing. You don’t need to get a loan to spend thousands of dollars on the project. All you have to do is likely buy a fitting or two and some plumber’s tape, and do it yourself. And if you’re thinking, “if only my local dangerous intersection was so simple,” consider: maybe it is.
