I'm walking up the middle of Wales for a couple of days. It's fascinating how the small remote market towns each manage to sustain one really unexpected business like a lingerie shop

I've been a member of Cycling UK since the 90s, back when it was the CTC. It's honestly humbling being featured in the newsletter of an organisation that's been part of my life for so long

"No consideration has been given to the historic nature of the city" says Gloucester councillor over cycle path resurfacing "It has changed the whole ambience of this area of the city" road.cc road.cc/content/news...

If you want a demonstration of how the stuff being sold as "AI" has no concepts underpinning its output - that is, no "intelligence" - try asking Copilot to draw a diagram and then ask it to create a PowerPoint slide with the same thing on it.

This is the table we sketched out when planning that article. You'll notice electric vehicles touch only one or two of the many issues arising from car dependency

Here's an interesting one. Objections to surfacing a path so that people can cycle on it. In part the objections are in case this unlocks the possibility of housing one day being built nearby without as much need for parking spaces (the horror!)

As in any factory, eliminate the need for dangerous machinery wherever possible; where this isn't possible, put in engineering and policy measures so that it fails safely. We do this everywhere else - we just have a weird blind spot when it comes to roads (see my pinned post)
