Eh? What? British resistance to change?

How about the Dunlop Maxaret braking system on the Argosy aircraft from
which the ABS braking system was developed?
How about the disc brake?
How about the pneumatic tyre?
How about east west engines with integral gearboxes - which configuration
virtually every other smaller car in the world now uses?
How about rubber suspension?
How about hydrolastic damping?
How about the first patented adjustable driving seat found in Riley?
How about the first car fitted with bumpers as standard?

ON A BROADER SCALE:
How about the first railway accident in 1828?
How about the first sewing machine in 1790?
How about the first television?
How about the first telephone capable of sustained articulate speech 1876?
How about the first iron steamship 1821?
How about the first vacuum cleaner 1901?
How about the first water closet 1589?
How about the first race on earth to speak English (in the proper form) as
its mother tongue?

All the above are British FIRSTS.There are many many more. I just got bored
writing them down. Fact is Britain is ahead of America - always has been,
always will be 'cos we're at least 2500 miles away and anywhere between
five and eight hours ahead  :)
What's more, 'Scottie' in Startrek is a Scot first and a British passport
holder. I guess Captain James T. Kirk knew what he was doing by recruiting
a Brit as his Chief Engineer on the Federation Starship. Are we really that
backward?
I don't think so.
