Should I be doing something about this?

I live on the oregon coast and there is a lot of commercial fishing and crabbing. My brother in law goes out fishing sometimes and he says that when you’re out in the ocean all day rocking back and forth, it still feels like you’re rocking back and forth when you’re on land. He said that he’s heard of people getting pulled over because it felt like they were rocking back and forth and they were driving erratically. I feel like this isn’t taken seriously enough and they think that just because they are not drunk then they are fine to drive but they are not. There could be God knows how many wrecks because of this and I don’t want it to be my fault.
