Decisions about fuel purchases are often irrational, much like many food purchases or generic medicines.

I know someone who avoids their local petrol station that is 10p/litre cheaper than most others nearby (within a mile or so) as they think the cheaper fuel must be lower quality. There are weird status things going on with purchases like this.

Only the other day my father refused to buy some branded paracetamol because it was ~5 times more expensive than the local pharmacy brand that was out of stock. (£2.25 vs £0.49 for 16 500mg tablets.) I'd usually agree with him but he was out of paracetamol and has been advised by his doctor to take 2x500mg a day and there was no viable nearby alternative.

A digression but for that generation (those born in 1940s/50s) that grew up with rationing I think it is hardwired into their brain to try and minimise the cost of so many things, but with lots of random exceptions. Later on that day he ordered an extra drink but decided he was too full once it had arrived so he left it. So he was worried about spending an extra £1.76 on paracetamol but not about spending £7 on a pint he didn't drink.

Many people decide what petrol station to use based on simply how close it is, what kind of shop is attached to it (and the bits of British snobbery around that), whether it also sells whatever else they want (bread, milk, beer, etc), or even whether it is easy to drive in and out of.

In France we had such api available for decades, many apps are using it and there are a lot of people using them.

I don't know if your experience is from British people but it looks like they just didn't have the mean to effectively compare fuel prices.

Once they do, there is a significant part of the British drivers that will most likely be using it.

Yes but the real feature that makes it viable, is that petrol station in France can change price only once a day. I forgot how it works in the UK, but in Germany they change wildly depending on the hour in the day. For example they show low price in the morning, so that workers who are late for work notice it and fill on the way back, only to find a price 10-20cents higher at 17h.

I don't see how that makes it uniquely viable in France. Germany has something very much like this too. And we've had it for nearly 13 years.

> Since 31 August 2013 companies which operate public petrol stations or have the power to set their prices are required to report price changes for the most commonly used types of fuel, i.e. Super E5, Super E10 and Diesel “in real time” to the Market Transparency Unit for Fuels. This then passes on the incoming price data to consumer information service providers, which in turn pass it on to the consumer.

As a consumer, there is no direct API by the MTS-K that you can use, but there are some services like Tankerkoenig which pass this data on to you. I have used their API in Home Assistant before I switched to an EV.
