Why is some of the ice outside very slippery and some of it not?

Fresh ice (especially the ones due to snow) is rougher than old ice. This is because fresh ice is formed when snow melts and freezes again. So it could be rough. But the longer it stays, the more opportunities it has to melt and freeze over again.
When the sun comes out, it melts the ice, it flows around like water, becomes smoother in texture and then freezes over again. This is how you can find smooth ice.
Another way you can find smooth ice is, if ice forms slowly over a long time (stairs), or if there is generally no disturbance in the surface where it is forming (lake).
