I have been commuting to work on the Sprint lately now that the weather has finally gotten decent. Left work today at about 3:45 because of a severe thunderstorm warning. I really didn't want to be caught out on the bike if I could avoid it. So anyway I am riding home on 84 West through Hartford. I am in the left most lane doing about 75mph. Traffic is moving easily and I really don't have many cars near me so I feel pretty secure. Just before exit 45 Flatbush Ave. (A left exit)I am just starting to pass a lady in a brown mini van driving in the center lane. I'm pretty much alongside her when I notice her tires drift a bit to the left an into my lane. People meander within lanes all the time so I don't really give it a second thought until I realize she's not stopping the meander into my line. I slam on the brakes as I am leaning the bike to the left to avoid her. (ABS works very well by the way). Once I get the bike back under control I hit the horn, give her the "What the hell are you doing hand gesture" at which point she pretty much does not even acknowledge that she nearly killed me and drives on like nothing happened. I was almost going to follow her and let her have it but I remembered the results of another incident posted here and decided to just drive home and vent my frustrations here.
