What Reason? - Update.
Why was this car parked on double yellow lines, on the pavement, at a traffic light and with hazard lights flashing?

Must have been something really important but I never saw any emergency services.
Before you ask, my passenger took this photograph.
Have you any incredible traffic photos or stories to tell? Please share them.
Twithay?
UPDATE
The car moved off but when I went back an hour later it was there again. It appears that the premises on the corner is being emptied. Not a good enough reason. Certainly not at peak travel hours.
