I mean, we have lots of traffic laws, some not so well thought out, others enforced capriciously, others not at all, and so on. I suppose we might as well just unofficially adopt the Idaho stop outside Idaho and to hell with other States' laws...

More seriously, I think the Idaho stop is a good idea. Cyclists won't stop unless they really have to for reasons fairly obvious to anyone who has ever biked on streets. No need to make that behavior illegal. But it will require a bit of an education campaign. And we already have a ton of things that require mass education: zipper merges, yield the left lane to passers, and so much else.

Should NYS allow bikes to make right turns on red too while we're at it?
