95% is way too high a target! I sometimes want to get supplies at the special Asian food store - there won't be one in my 95% neighborhood - nearly everybody has enough of their own special hobby/interests that they cannot live 95% in their neighborhood. Note that I only counted for me - in the real world most people are in a marriage like relationship, each of the pair has their own interests and different jobs.
What we should aim for is everybody is in walking distance of 5 restaurants, 1 grocery store, 1 general goods store, 1 library, 1 elementary school (but not higher level - after about 6th grade students benefit from larger schools where they can take classes different from their neighbors), 2 parks, 3 churches. Then put them in close walking distance of good public transit so they can do other things that they do in life all the time (Note in particular going to work every day is not in the above list for most!). You should of course debate exactly what should be on the list and exact numbers, but the above is a good starting point.

Agreed. I did mistype what I was thinking though. Not 95% of destinations one might ever want, but my thought was 95% of trips. Nearly all my trips are routine, either to/from office (bikeable) or supermarkets (walkable), movies/library/restaurants/misc shops (all walkable), parks/sports (walkable), basic medical care (walkable).
I certainly have hobbies/needs I must to drive for, but those are fairly occasional trips. My thought is that if we as a society make it so that nearly all routine trips can be local (walk or bike) then the exception will be rare enough that we don't need more road capacity.
