Sorry if I haven’t read every topic that has been created, kinda new here, jeez.
And so far the majority of responses have been for random encounters, so keep thinking everyone agrees with you.
It will eventually drift back to the same outcome (I'm presuming this because it has most every time). However, in the off chance it DOESN'T, Bethesda will probably not implement this anyway since many people would have a [censored] fit if they couldn't at least fast travel.
However, for my opinion; if something like this would be implemented then fast travel and carriages would immediately become needless (you might as well just walk it yourself and get waylaid), thus it sort of cancels itself out because it cancels out the point of fast travel. I would rather they improve other aspects of the game, which need to be addressed as urgently as possible.
And no, I'm not mad at you for starting this thread, I'm exasperated that somehow these topics keep coming up.
