Laws can be dumb, if there are no other cars and you roll through a stop sign why is that unsafe? This is also called California stop. People in California have places to be and it's a big place so the effects compound.
As soon as you make the rolling stop legal people will push the limits of that law and drive straight through if they think the way is clear.
The numbers of drivers driving through reds (at least here in coastal San Diego) has noticeably increased over the past two years, previously people would hit the gas if the lights turned yellow, now they are hitting the gas if they see yellow (and crossing through the intersection on red). Accident statistics seem to back that up https://www.cnn.com/2019/08/29/us/red-light-deaths-trnd/inde...
Making traffic rules less strict seems like a recipe for more accidents and deaths.
Traffic lights are a completely separate issue. The cars are traveling much faster. At a stop sign you will have much more time to react since you're going 5-7mph max.
I don't think there are any federal laws about traffic signs. California's laws require you to come to a complete stop at stop signs. Programming a computer to intentionally break the law "because I have places to go" seems like poor judgement to me.
