i was riding through Cambridge, Ontario on my way to a bicycle shop. That bicycle shop was on the other side of highway #401 which is a major highway. There's an overpass with a protected bike lane on it. The thing is the bike lane is on the far right of the road and actually goes to the right of the on-ramp to the highway. there are a LOT of BIG trucks using that Franklin Blvd on-ramp. talk about a dangerous bicycle lane.
So, NO! in many cases I do not use a bike lane. This is especially true of the many "Door-zone' bicycle lanes that I see.
Cheers
