Regardless of what mode of transportation is being used, people will eventually do dangerous stuff. We can make outcomes from these actions safer for everyone if we minimize potential points of contact and make efforts to actually protect those who are most vulnerable even if it comes at the expense of the convenience of some other users (specifically in this case, cars)
My god someone nearly killed me and my family on the interstate because they were going the wrong way in their car but to listen to some people a person on a bike doing a rolling stop at a stop sign is just as bad.
