"My favorite driving holster is a fanny pack. The pistol is laying right in your lap with very fast easy access. No, they aren't stylish, but I don't much care what people at gas stations and rest stops think of my sartorial decisions, and it is easy to move the pistol back to another holster (IWB for me) when I get somewhere that appearance matters."

@AutoS,
Just some observations for your consideration. Here are some of the things I considered --
In 1986 during the Miami Shootout with Platt & Matix, one of the FBI agents had removed his revolver from its holster and placed it on the seat beside him. When his vehicle came to a sudden stop ramming into the adversaries' vehicle, that firearm slid off the seat and was flung up under the dashboard, far enough that it could not be retrieved during the firefight that followed. I don't want my firearm slid in between the seats, in the center console, in a steering column clip, or otherwise not immediately on my person for much the same reason: just in case hostilities commence with some sort of vehicular collision. Just a personal choice.
(I also don't want to leave it in the car during gas stops...)
If I need it while driving, trying to draw suddenly from an ankle holster while avoiding a collision or some other form of evasive maneuvering resulting from a 'road rage'-type encounter is sub-optimal.
If I need it while out of the car, as noted above, kneeling down, hopping on one foot, etc. are also sub-optimal (IMHO).
Upon reflection, I couldn't think of a single scenario either inside the vehicle while in motion or outside the vehicle where an ankle hoster was clearly the optimal solution.
For an option that works well under nearly any set of circumstances *while traveling on extended road trips*, I found a fanny pack to be both "gas-stop friendly" as well as tactically sound in various circumstances.
Your mileage may vary...
