The nearest supermarket to me is a massive Tesco. The second nearest is a Lidl. I’ve taken to walking the extra five minutes to Lidl lately. Partly, it’s because the quality is often better. Partly, because it’s cheaper. Mostly, though, because it’s much less stressful.
Transport for London are running a campaign urging cyclists to make eye contact with drivers. It’s a great idea in principle. Unfortunately, it’s not possible in practice.
