We had to merge into single lane on a curved ramp at La Guardia Airport in Queens, New York, (near American Airlines) We had the right of way and this other driver saw us before I could see him. (Our car was ahead of his.) He blared on his horn nonstop behind us, and then got into the left lane following right next to us, blaring his horn nonstop again because he was mad that we were in front of him before and now he wanted to get in front of us. He was acting aggressively and erratically, trying to engage in a fight with me. We refused to interact. This was a very dangerous ramp we were on, and the safest thing to do was to drive slowly and stay out of his way. He quickly cut in front of us, squeezing half his car in because there wasn’t enough room, but he didn’t care. We saw that there were three black haired males in a black Nissan Altima, Virginia Plate TFY6300. Once they realized that pictures were being taken of them, they decided to escape by quickly cutting into the right lane and exiting. Where are the airport police when things like this happen? This driver acted like he was drunk or on drugs. The airport should be a safe place for everyone.
