And in these burbs, myself and my kids have almost been killed riding bikes on the sidewalk, because people don't stop before the crosswalk or look going in and out of driveways. (No seriously, both kids have had to dodge cars entering the crosswalk without stopping at the line). When riding on the streets with me, nothing even close to that.
A cyclist using a full lane is the right and proper way to cycle (ever since the 1800's). They are not obstructing traffic, they are traffic. The bike isn't going to cause a crash. The person driving 45+ around curves without slowing down will be doing the crashing. You shouldn't single out bicycle from the legal road users group that could also be stopped or slow at any given moment on the road.
