But that would signify there is an impact? And that you are crashing at 1m/s, if you don't enter in contact? If I'm in my house, I am not moving at 130km/h from the highway near my house?

If you are looking at someone through the portal, they will appear to be standing on a parade float. They are standing still on a surface, but that surface is coming at you.

You won't feel any change in momentum as the portal passes around you, but the ground will be suddenly moving under you.
