Well, RayB, you'd be wasting that time anyway, car or bike; while I understand the frustration of stop-n-go, I've seen the vids of Tokyo... YIKES! Like Times Square on New Year's Eve ALL THE TIME! There IS no such thing as efficient travel there!
Now, to the general OT discussion (i.e., the Idaho stop...):
On the face of it, the Idaho stop sounds good; as I understand it, it's like the right-turn-on-red law -- stop, make sure traffic is clear, then go. But, like the RTOR, it will soon be lost on the practitioners that YOU HAVE TO STOP FIRST AND YIELD TO ALL TRAFFIC!
I have seen, over the last 10-15 years, a legion of drivers jump out from a red to get ahead of traffic they didn't want to wait for, and then belligerently holler about their "right" to make the turn on red! I've begun to believe that the RTOR needs to be repealed because of the rampant stupidity of entitlement.
So, bottom line, I'm not in favor of the Idaho stop.
