Why do men wave and honk at me from their cars?

i have a conventionally attractive body (which means my body type adheres pretty well to conventional beauty standards. I am 5'6" and i weigh 115lbs. not saying my body is attractive because my boobs are smaller than average) and i would rate my face as average. Sometimes if I'm walking somewhere or working in the yard or just getting in my car, honk or wave at me or break their necks to look at me while they're passing, yet i rarely get attention from men in the grocery store or anything like that. im not gonna lie i want a guy to talk to me so bad. i'm extremely lonely and always have been. i doubt anything would come being approached, but i still want it. why are they brave enough to wave and honk from their cars, but not brave enough to approach me?
