What??........... even the cheap Sears made campus bike I shared with my older brother in our early days in college (yes,......we were poor boys) was a treat to ride with no hands.....better check you frame alignments and your headsets for adjustment or straightening. Also see if you brake cable routing is putting too much pressure on one side of the bar too.
Both my PSV and Vitus Carbone also ride nicely without hands on the bars, more the Vitus than the Peugeot though....for some reason.
BTW, the usual "crown" running at the center of roads that is for rain water drainage, do make it neccesary to sometimes compensate with a little bit of lean towards the center of the road, depending on how big the crown is.
