Radar is a tool. You might not *need* it, but then, that doesn't mean that it can't be
very useful indeed to those who do have it. The more times you find yourself in
questionable circumstances, the more useful that tool can be. The fact that so far, you
have survived without it, is commendable but doesn't really speak to the issue of whether
that tool is useful and might increase safety & reliability.

I seem to recall the same argument faced shipboard chronometers in the
18th century. After all, a perfectly good "lunar" method of
determining longitude already existed and was backed by the Astronomer
Royal...the fact that it took several hours of fairly advanced math to
calculate presented no problems...on land.

Use what you need. The reasons are your own.
