Tyre Frustration: Where do I put the data?

The Prius needed an MOT, apparently according to the newly published data, tyres and brakes cause the most MOT failures in my particular model of Prius. Hurrah to the DVLA for finally releasing the data. But that's another Blog "The value of joining public and personal data"

So anyway I checked the tyres, and lo I found damage to a sidewall a possible MoT fail. I then spent an inordinate amount of time researching the tyres I should put on the Prius. There is now a whole section in "mybrain" devoted to the data gathering effort. Thanks to the EU we have new data on Fuel Efficiency, Braking and Noise created by tyres, sadly they have not furnished us with the the missing Rate of Wear data. (I suspect the industry fought hard to keep that from us, or perhaps it is inversely proportional to the Fuel Efficiency impact and governments are keeping the data from us) No matter how hard I looked I could'nt find the data. Frustration growing... Data should be easier to get than this I should be able to just ask my agent. What are the tyres that will give me, great braking, the best fuel efficiency to wear ratio, and who is the cheapest supplier?

I eventually found the tyre I've gone for a set of Falken ZE914s C/B/70dB from ctyres.co.uk, they have now been fitted. I also had the car serviced they found two of the wiper blades split, (note to self check the wiper blades before the next service) They gave me a piece of paper with lots of very useful data printed on it relating to the safety of the Prius, including 12 point depth check of the tires. Try as I might I could not find an A/A/70 !!

But all that is the build up. I now have a lot of potentially linked data most of which is embedded in the text above, that will be useful to me later and some of which I would be very happy to make public. But where the heck do I put it all...

If I don't store it all now how will I be able to ask my personal agent...

"How long did those first Falkens last?"
or
"How many miles did the last set of tyres do?

The answer is clearly that I won't be able to....

So I want a personal data store, and I want it now!!!!

Otherwise it's going to take a while longer for my personal agent to be useful to me, just asked SIRI he didn't have a clue. But then what should I have expect from a cyber butler whose only focus is pleasing it's real employer: Apple, and who clearly doesn't have access to my personal data.
