Yield Shmield

Just a quick post tonight. I just wanted to say how much I hate yield signs. I mean seriously, if I see a yield I stop, b/c if I don't and someone is coming, I'm going to get t-boned. So why not just put up a stop sign? Why? I mean it's like putting up a sign that says "well, maybe you should kind of be careful, but you don't have to if you don't want, but if something bad happens, we'll say I told you so".
