I experienced the same thing with a '80 Vette I used to have. It has something to do with the tires too. Shape of the tires + cuts in the concrete and car wants to slightly wander.
Isn't that called tramlining, or am I getting mixed up with something else? Where your wheels sort of "aim" for the groove in the road. Wide tyres will do it a lot more than narrow ones.
