If you skid, you were going too fast for the conditions and you, as a licensed driver, should know better...

I don't know what the I-5 is like but here, you drive no faster than what is safe for your vehicle, regardless of what speed other people are driving. Most streets where congestion is possible have more than one lane, and the convention is that the right is the cruising lane and the left is the passing lane. If others can drive faster than you, they may pass you on the left so there's no reason why your speed should hold up traffic...
