Your situation seems baffling to me.
I have a VDO temp gauge and sensor, and my readings don't vary whether I'm driving or stopped. As far as I know, the portion of the sender that actually takes the reading is inside the
oil pan and not exposed to air flow.
Looking at the SpeedHut sender it looks like it would be totally immersed as well:
I suspect there's something else going on. Does the wire have a solid connection to the sender? Could it be moving around or grounding against something while the vehicle is in motion, but not when stopped? Looking at the impedance / temperature chart, zero impedance (e.g. grounded) would display cold on the gauge.
