There are many important issues in our economy and on our stock markets that need to be addressed. There are also a host of smaller, nagging, annoying little problems that should raise all our hackles.

Well, at least they bug Motley Fool co-founder David Gardner. In this series from the Rule Breaker Investing podcast, he takes aim at several tiny yet very irritating quirks of the market and the wider economy.

This segment features two annoyances for the price of one. The first sees David unveil his "Gardner's Law" for advertising, while in the second he expounds on proper behavior in traffic.

A transcript follows the video.

This podcast was recorded on July 20, 2016.

DAVID GARDNER:

No. 4 I've named myself. I came up with this on my own, so I call it Gardner's Law. This may be the first public unveiling of Gardner's Law, and here it is.

This is specifically aimed at sites online that have stuff. They might have stuff that you can get from them, and they call it cool stuff. Like, hey, click here for cool stuff, or get cool stuff in our store.

And here's Gardner's Law. I've actually written this one out verbatim, and I quote: "Any stuff that is referred to, particularly on the internet, as 'cool stuff' is, by that very fact alone, completely and inherently uncool." I think we can leave that one right there.

No. 5 might sound a little ridiculous -- and yeah, it probably is just on the face of it -- but if you think about the consequences of this, and you just compound it across a population every day, it's more than ridiculous. It's a little higher.

And that is (I hope you share this pet peeve with me, and I know you don't ever do this yourself) drivers who don't use their turn signal. I will admit that I am a pedant in a lot of ways. I'm an exact, kind of precise person, and I literally do try to use my turn signal, even in my own driveway, every single time that I'm ever moving left or right.

Part of it is (I will admit this) that I am a fairly aggressive and fast driver, so I think it's very important for me to signal what I'm doing to people around me. But I think it's really important for all of us, regardless of whether you're a fast or a slow driver, to let people know if you're going left or you're going right. It's not just courtesy -- it's the law.
