That's fucked up what happened. People have no god damned lives. I get road rage but I never wanna stalk motherfuckers for it, certainly not a cute girl such as yourself. In that situation you coulda hopped out and just screamed towards him. No words in specific. just AHHHHHHH FUCKKKKKKK He'd think you're nuts.
Holy shit! I'm glad to hear you're okay; they guy who followed you sounded like a serious creep.
My advice to friends who get followed, is to drive to their nearest police or fire station and stop there
for back-up. With any luck, they'll get the message. Nobody has a good reason to follow anybody without an invitation.
