As a driver, the bike lanes where bikers do not yield to turning vehicles as they should and assume they have rights that even pedestrians don't have, are a big enough concern.  I could get on a bike.  Doesn't mean I know how to ride one safely or legally.  

I've noticed one thing in seeing the bikers on King Street...they dress for riding a bicycle.  Is there any guarantee a person wanting to rent a bicycle knows how to ride a bike well enough to keep from hurting themselves, or others?  Is putting people who aren't used to riding a bike (if they were they would likely have their own) on the streets (not sidewalks like may people do now), with cars seem like a wise idea?
