I happend to spit in someones open car window as they ran a red light a good 5 seconds after the change with me crossing on the green in NYC. I was actually surprised my aim was good. I figured I'd just get the vehicle. Next thing I hear is screeching tires braking. I continued my ride so I never got to speak with that person. I'm think mine was worse because that car was moving and to have something hit you while you're driving even if it is just liquid can be scary. I regretted it afterword because then I'm at their dumb level. Sometimes we let our emotions get the best of us. I guess it has something to do with being close to being injured badly or killed because someone in a car is dumb. I have a friend who rides motorcycles and sometimes change falls out of his pocket accidently hitting cars that give him close calls. So spit is better then a bunch of pennies hitting your windshield at 60 mph.
