If you’re looking to show off your driving skills in Grand Theft Auto 5, there are a few things you can do to help. One is to honk your horn at other drivers, which will get their attention and make them stop. Another is to use the car’s loudspeaker to blast rock music or rap lyrics at other drivers, which will make them take notice and maybe slow down. Finally, if you’re feeling particularly daring, you can try honking your horn while driving in a race or competition.
