Motor vehicles need to respect cyclists

I went for a Martin Luther King Jr. Day bike ride. At hour three, a truck pulled up and threw a bottle of urine at me. I lost my balance and did not get the license plate number. My helmet, my fluorescent vest, my bike, and my bag filled with snacks and my cancer biology textbook were covered in urine. I pulled off the road and found someone doing yard work to stand with me until I recovered. After getting back on the road, the truck drove toward me again, and the passenger, a teenage boy, casually yelled "sorry." But I do not think they were sorry when they thought I was just a body on a bike.
