Never had anything thrown at me nor ever even been "buzzed". Had a carload of young women once yell at me but what they yelled was "nice a_s!" so I wasn't particularly offended.
Coffee, soda, candies, coins, but the weirdest was a fast food wrapper casually tossed over the roof as a car passed on my left. Pretty harmless as it was paper but I did catch up to the car and it was an older middle aged Asian woman in a business suit. Totally unexpected and I never did get her to look at me.
