**As of the GunRunning update (1.40): Works**
The one race playlist method was patched so many of us who want to be at ease while selling product and moving supplies were left to the brutality of public lobbies. Real ones. Well fear no more for I've found a way to get this type of thing to pop up on your screen:
It all starts with the wireless/wired connection method. Here is the original method:
-set up wireless connection/unplug wired connection/be sure to be connected to Xbox LIVE.
-enter a public lobby
-plug in wired connection and instant empty lobby!
That method doesn't work anymore as far as my testing goes. It does have the off-chance of working but you're most likely to get kicked back to Single Player and being told you lost connection to Xbox LIVE. Here is the slightly modified version which, so far, has worked really well for me.
-Go to Network Settings and turn the option "Go Offline" and then back to "Go Online". At this step you should be using wifi.
-Start GTA V up. Load into Single Player and then head straight for Online.
-Once in a lobby, put in a wired connection and watch everyone disappear!
There was some fiddling to do but I finally found how to avoid that "Returning to Single Player" message. Please let me know if it works!
