The expression is Internet Drafting. I searched for it in Google but did not find my usage.
Internet Drafting: The act of using the public Wireless Internet facilities located a moving vehicle (say a Greyhound bus equipped with public wifi) from another vehicle following the networked vehicle closely to stay within signal range. Similar to Race Car Drafting.

Your thoughts and observations are welcome. Be gentle though I am new to the site.
