Sainsbury's Local is now open in Gloucester Road, so you can "shop locally" without having to go into local shops. Of course, any one who does this will miss out on the pain-au-chocolat which the Bread Store has raised to an art, but sometimes you're in too much of a hurry to queue for them or talk to the staff.
What the new shop does have, and presumably will have the cyclists and students of Bishopston happy, is a contraflow bike lane just next to the shop, here on Elton Road. You can just see it under the HSS Hire van NA09EZJ.
Presumably the driver was worried about cyclists in a hurry endangering these new shoppers, who would be unused to such things, so he has positioned himself for the safety of these pedestrians. The fact that he is wearing hi-viz shows he recognises how cyclists on a the pavement can endanger pedestrians, and how it is important to be visible to them.
