tOk, Small sample size...i.e this mornings commute.

A street I routinely ride on my morning commute just got resurfaced and has no markings other than little temporay reflectors for the center line.

The street is pretty broad and has better than average bike lanes.

Without the bike lanes (and overall lane markings) drivers came a lot closer to me than normal, while i maintained a street position that would match where I would be with the bike lane.

Just a small bit of observation, but it supports my belief that bikes lane provide the most bang for the buck in terms of infstructure.
