Depending where you live, I think much of the frustration directed towards cycling is a result of local Government sacrificing driving freedoms (efficiencies) to improve cycling infrastructure.
Vehicle lanes and parking spaces are reduced or removed in order to fit a bike lane. Speed limits may be reduced, turning restrictions increased and entire streets may become off limits to motor vehicles.
All great improvements for cyclist, but if poorly planned, daily driving becomes more stressful for many. As we know, share the road is not always well received by intitled drivers who think roads are for cars only.
