Just Got Back From the Police Station.

Yeah man, the guy sounds nuts. Please remember though that there are even way more insane people than that running around. Some carry guns etc....
It's best to just avoid confrontation at all cost. You actually got lucky that nothing worse came from this. I just move over and let these Nutballers go around me and never see them again. You can do what you want but I recommend you rethink how you handled this whole situation.

Well my normal handling of the situation would've been to get out and beat this guy's a$$ but I had my wife with me and this was the first time she experienced anything like this so she was scared. Also, I did try to let the guy go when I let him around me when he was passing me. That's all I could really do, but it didn't help as he just jammed his brakes on, came to a stop, and tried to get us to rearend him...I mean what else could've I done, really? I was already on the phone with 911.
He was intent on trying to do something anyways, no matter where I went or where I stopped he was going to have his way one way or another. So what else was I supposed to do???? It's not like I asked the guy to follow me or something.
I agree with you that there or even more nutty people out there and the thought of this guy doing something even more stupid (like having a gun) is part of the reason I called 911, that and it was dark on a semi-lighted street.
