BOOTS, I grew up outside of NYC. It's a tough town with its share of crazies. If this jerkwad was crazy enough to think he's a man because he's willing to take on a bike with his truck, he's crazy enough to carry a gun or other serious concealed weapon that he would use on you without hesitation. Take the advice about writing down the license plate and either report him or find out who he is and handle the situation when you have the upper hand. Reacting while he is provoking you is exactly what he wants. My recommendation, think of yourself first, and take him on, on your terms when your not on your bike. Keep safe!
