It seems like you are referring to a popular internet meme known as "This is Bob." In the meme, Bob raises his hand to wave hello when a car goes by, often accompanied by the text "this is bob bob says hi." The hand gesture is a simple waving motion to greet the passing car, and the phrase "this is bob" is a humorous way to introduce the character in the meme.
Well, Bob needs to work on his communication skills because that sentence is a hot mess. But if I had to take a wild guess, I think Bob is trying to ask how to do the hand wave thing when a car goes by. So, to answer the question Bob probably meant to ask, you just raise your hand and give a friendly wave as the car passes by. Easy peasy, Bob.
