Here in California we have Stage 2 vapor recovery systems on the nozzles in most urban areas. My filling the tank is a two-handed affair, and I keep a pair of gloves in the trunk to help.
1. Insert nozzle in tank so that the nozzle just catches under the far lip and rests against the near lip. Keep contact to assure grounding.
2. Pull the vapor recovery sleeve back a couple of inches with one hand. You need to keep pulling it back or the spring will allow it to close. Yes, this breaks the seal and negates the usefulness of the vapor recovery, but that's life.
3. With the other hand, pull the pump handle. It won't engage if the vapor recovery sleeve isn't pulled back far enough.
4. Listen to the fuel going in, and when it sounds like it's full, it probably is. With the nozzle inside the tank wedged against the far lip the vapor recovery system will click it off when about 1/2" below the neck.
When I'm filling from the left (my preference), generally my left hand is on the vapor recovery sleeve and right hand is on the pump handle. Opposite side filling, hands are reversed.
BTW, if you are tempted to push the nozzle down into the tank to open up the vapor recovery, tread carefully. The bail for the gas gauge is down there and you can snap it off with the nozzle. Don't ask how I know that - painful mistake with a steep learning curve.
