So the design flaw seems obvious--the motor vehicle lanes are narrower than British standards, and from the standpoint of the cyclist, probably make the bike lane less safe because of the likelihood of a car or truck swerving into the bike lane to avoid a head-on with oncoming motor vehicle traffic.
There appears to be a rather wide walk lane/sidewalk on the left side of the picture. Some tinkering with the dimensions of all of the lanes should solve most if not all of the problem.
