Context: Today I was driving up 14th St. near Kensington Road , going about 60 km / hr , when some moron hurled a full ( but open ) beer can at my windshield . It hit near the center and spattered beer everywhere ( which quickly made my car smell like beer , since my air conditioning intake just sucked it in ) and I pretty much slammed on the brakes . I was sooo lucky that the people behind me were paying attention and did n't rear - end me .

Question: Why did I pretty much slam on the brakes ?
