Earlier quoted context omitted.
As long as you are okay with fining cyclists for riding on sidewalks, failing to come to a complete stop at stop signs, failing to signal turn direction, failing to yield, etc as well. Same with pedestrians for jaywalking. You can’t be intolerant of vehicle mistakes and allow for others if you actually care about safety.
Actually when you drive a car, you have a lot more responsibility. It is easier to cause serious harm to someone while driving a multi-ton vehicle, than when riding a bike.
For example cyclists have caused serious harm and even kills pedestrians before. Also pedestrians and cyclists have caused serious accidents to motorists when causing car drivers to react suddenly, to swerve or break harshly which has resulted in those drivers colliding with other motorists.
Just to be clear, I'm not saying the level of responsibility between pedestrians, cyclists and motorists are equal; clearly they're not. But there is still some shared responsibility when talking about road safety.
