Fuel Finder: “It shouldn’t have left the testing environment – in fact, we are the testing environment” Four days after its official launch, independent fuel retailer Johnny Srikrishna is experiencing such fundamental issues with the government's Fuel Finder service that he has declared the system "shouldn't have left the testing environment".

I’ve have every sympathy with this chap. If I had to struggle with Fuel Finder under threat of the law, rather than just spend my day casually looking through line-by-line to work out which bits are rubbish, I’d be apoplectic. It is like a satire of GDS-compliant API provision in the vibecoding age.

The voluntary scheme always had the Morrisons in Gibraltar in it.

It looks to me like they swapped all their URLs over the weekend so my code broke. If I had to use this under threat of legal penalty, I’d be even more annoyed than I currently am.

At least one in twenty car miles driven is now zero emission More than one in twenty car miles in the UK is now driven by a zero-emission car. Analysis by the RAC Foundation shows that at the end of 2024 zero-emission

>1 in 20 UK car miles is now zero emission

We have updated the
@racfoundation
#GreenFleetIndex to the end of 2024

5.3% of car miles are zero emission vehicles (which are only 3.8% of the fleet)

EVs now neck and & with diesels in annual mileage terms

relatedly, i wish the ICE goon squads they’re allegedly sending to seattle all the best hiking up capital hill

I agree with the gist of what you’re saying, but, technically speaking, what about Greece? That’s got some fairly horrifying levels of centralisation.

I'm looking forward to starting work with Agilysis on this Road Safety Trust grant to the RAC Foundation to match STATS19 vehicle records with admin/commercial data to explore the links between deprivation and vehicle technologies, histories and characteristics. (lnkd.in/eqi6m92C) #roadsafety

Tracking the Buses in England by @OpenInnovates

open-innovations.org/blog/2025-01...

We've got data for everywhere -2 weeks in September 2024- but the tool only works for The North West and Yorkshire & The Humber - hit us up if you want to do more with this data, infrastructure & tools.

If your stuff doesn’t make the next Quantum of Sollazzo email (@puntifisso.bsky.social), then it’s a grave injustice.

Maybe I’ve had a long day and I’m being especially miserable, but we should learn our lesson and plan for self-archiving of new stuff as it appears. Perhaps a job for CIHT, UTSG, etc.

You’d hope so! I’m currently trying to think through how to plan for soon to arrive fully live petrol station data and soon to arrive live EV charger use data and aim off for the inevitable problems with archive sharing with those….

I reckon it’s been about 8, plus or minus 1. I didn’t ask about timetables, just the locations archive.

…(b) that Waymo itself doesn’t seem to have a remote kill switch or (c) that he can’t press the button on his app as directed because the moment he got taken hostage by his deranged Waymo, he thought “this would be great on Instagram”.

Not sure what’s the worst thing about this: (a) this man trapped in a robo-taxi endlessly driving around a car park roundabout, … (1/2)

VW Suffers Major Breach Exposing Location of 800,000 Electric Vehicles A massive data leak involving over 800,000 Volkswagen EVs has left sensitive user information unprotected on the internet.

Who could have predicted that something might go wrong with cars sending vast amounts of user data back to their makers?

Because London has rubbish quality of reporting and high frequencies of services, London really does pop out of the map.

I’m only testing with 3hrs so far, but there are obvious issues in mid-wales, Norfolk etc, but, ranked by operator, TfL is second worst for % of all breadcrumbs that are either the start or end of a blackspot. First and third are in Peak District and Dales.

Black lines are where the bus didn’t report for 90+ seconds and in that time travelled 300m+. Actually easier for me to spot an intermittently spatial issue (like phone blackspots) this way than via a map. Got the idea from a recent #quantumofsollazzo email.

This definitely the counterpoint to the UK “transport is better in London” discourse, @tomforth.co.uk. London is an off the charts mess in this respect.

Currently looking at UK BODS bus location data to examine where the blackspots are. Spotting some fairly consistent spatial issues like here (the inbound TfL 265).

Nothing says Saturday night in your 40s like trying to perfect your Marey diagram of UK bus punctuality in ggplot2.

Also sorts of troubles I had were in fact just crap sleep. And I learnt that you can be asleep but not get any of the benefits of it because of how you go about it. My machine has a SIM card and sends my usage data in, so I don’t even need the annual checkup (unless something is actually wrong).

Yeah. CPAP is amazing. Totally changed my life, cured long history of depression/anxiety, I think much more clearly, stopped bruxism, feel hugely better.

Told, forget it, go home, we know what’s happening. It was a hugely life changing event for me. I’m so glad I did it. Was totally sorted out and normal again with proper treatment within the month.
