>>do you know what a 13mm ...
More to the point, what's a mm?
(yeah, bad joke)
Amazing how tech goes around. By the turn of the century it was getting tough to self-service a car because so much of it's controlled by chip, needing special $10K service computers to access diagnostics. And then... in recent years devices costing $30 came out that can read most vehicle diagnostics. Of course people bought their own to give them leverage over service shops claiming this and that needs replacement. Now I see bluetooth devices with no screen that interface to your phone, for as little as $5.
All this, just before the true electric car revolution with only interval servicing needed on a vehicle with a few dozen moving parts that can be expected to last 500,000km (what's a km?!)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
