I believe that
@RobWard is a bus driver, in which case he will find getting past on-road cyclists more difficult than will a regular motorist. With also being under pressure from the company to keep to timetable, I can see why he's seen fit to ask about cycle track usage.
In my case, I view the standard of UK cycle provision as generally being so low that I'll only use a cycle route or facility if I've previously sussed it out as being useful to me. If out of my local patch, that means they don't generally get used.
