I disagree. The Idaho stop is a very real law and it's been proven safe. There absolutely should be a different rule for cyclists and we already have decades of proof that it not only works but increases safety.
Also, pedestrians don't stop at stop signs currently. It's perfectly legal for them to continue without any kind of stop and I'm not aware of any place on earth that requires pedestrians to stop or has ever given a ticket for the them failing to stop.
