It is definately not normal for all buses to pull to the left.  That is 
ridiculous.  There could be a number of causes, though, such as uneven tire 
wear (or different sized tires), the need for an alignment, a dragging 
brake caliper, worn front end part, etc. etc.  The most lilely causes 
should be relatively inexpensive to fix, I believe.
