If you are asking that means that you likely do not have a good relationship with your neighbor or you don’t know him/them.
Unless it is something serious, I would buy or make some cookies and take them over for a brief chat. If you aren’t getting along, mend fences. If you don’t know them, introduce yourself. Either way, you’ll let him know that another human being lives next door and most people don’t want to offend people who they know.
If the guy is an a*s then he’ll continue to get clippings on your vehicles. If he feels that he “knows” you, he’ll become more conscientious unless he’s anti-social anyways. Life is too short and you might need his help (or he may needs yours) one day.
