1. Because the people who don't want fast travel are the minority. You don't HAVE TO make a mod to disable it, you can simply, not use it. Duh.
2. PC graphics are not held back because consoles play games on medium settings at best. PC users can set them to the fullest.
3.Consoles can output resolutions up to 1080p. The individuals screen will very, but the common factor is that people are generally sitting further from their TV then PC users are from their monitor. So they have to make the UI bigger to account for this distance.
4. Saying PC users are the biggest market is laughable.
And this is all from a strictly PC gamer.
I don't think you quite understand the issues here.
1. The integration of fast travel not only diminishes the overall immersion of the game, but also has many other ramifications as well, since the game is designed with this in consideration. Simply not using it or even disabling it isn't optimal.
2. Of course PC graphics are held back. Did you not hear them saying it will look more or less the same across all platforms? Even at highest settings I doubt the game will look as good as it could, considering PC is leaps and bounds ahead of consoles.
3. Yes, people do sit far away when looking at TV's and close for monitors. So all they have to do is make a proper PC-formatted UI for the PC version, which will actually be much simpler to make since they don't have to scratch their heads about portraying information and controller navigation. A proper PC UI should not be too much to ask.
4. Saying PC users are the biggest market is laughable is laughable
