I've read before that converting many stop signs to yield signs, even for cars, would save all sorts of energy without significant increases in accidents.
I think that all depends upon the traffic pattern at that time at that stop. One stop light where I used to live would convert to flashing yellow at 10pm and back to a stop light at 5am.
With a bicycle it's all about energy conservation.
I don't agree. And with traffic laws it is all about predictability.
Everyone involved needs to have the same understanding of who has the right of way and why.
As such, I typically have much longer to assess an intersection before I reach it, my stopping distance is extremely short, but if you make me stop it extends the time I'll be in the intersection when I DO cross significantly.
So?
There are only a couple of factors in play:
1. Do all the drivers / cyclists / pedestrians have the same understanding of who has the right of way and in what order?
2. Do all the drivers / cyclists / pedestrians have the same understanding of whether the intersection is "clear" for them?
If I'm allowed to use a stop sign as a yield, I'll attempt to time my passage such that I'll cross near my maximum speed, clearing the intersection expediently.
And that is the problem. You are no longer predictable to the other drivers / cyclists / pedestrians. You might stop or you might not stop.
Being through quicker reduces the chances I'll be involved in an accident there.
No it doesn't. The same as it does not make it safer for pedestrians to run across the intersection just because they're on a crosswalk.
Whether it is safer depends upon whether the other drivers / cyclists / pedestrians know where you are and have the same understanding of who has the right of way in what order.
The ONLY way that this change should have any positive change is if a driver would NOT have seen you when you were stopped BUT was far enough away that you could cross BEFORE he entered the intersection. In which case YOU need to work on YOUR visibility.
