Honestly, even setting aside the war ending and with the fuel shortages, Russia can do things regarding fuel distribution. They're gonna have to set something up regarding rationing that doesn't have people just sitting in line at gas stations. Like, "here's your allocated amount of fuel and here's your time slot to get it".

Giving priority to whoever waits in line the longest is a really high overhead method of allocation. It's kind of on the Russisn government that they don't have anything in place.
