is there a real time travel tracker website?

[jazi]

My significant other is currently driving from Oregon to me in California, I'm manually tracking where he is by using google maps and moving the marker every few minutes compared with how long it will take him to get here.

So, My question is; is there a website that has this concept (real time auto tracking?) out there, I can't seem to find the right words to google it.
I'm not talking about tracking him by GPS, just about how long it will take him to get here with a little car icon moving on a map or something.... ugh why cant I explain this concept!!
