There should be real forms of travel (the ever-present "It breaks my immersion!" and my own peace of mind so I don't have to read four hundred billion threads over the next years complaining about fast travel like with OB), and it shouldn't be that hard to code an NPC to cart you between City X and City Y.
Fast travel was already optional! There's no need to disable a feature you can just not use. Is something forcing you to hit a location, click it again and hit "go here?" Just use the map screen as a map screen, not Cyrodiil Taxi.
