British vs American Pronounciation

[kuchmarekova]

Hi there!
I've found it very interesting, but can't explain in a correct way, why it happens.
There are some words which must be pronounced in american and british variants differently, for example:
dance AmE /a/(frog) BE /ɑː/
can't AmE /a/ BE/ɑː/
globalisation AmE /ai/ BE /i/
etc.
There is a tendency even between native speakers pronounce such words in an American manner.
How do you pronounce them? Why do you think such a tendency exists?
Let's make statistics within the users of this web-resourse.

I speak BrE, and I pronounce them dɑːns, kɑːnt and ɡləʊb(ə)lʌɪˈzeɪʃ(ə)n with no Americanization and I don't know any BrE speakers who do Americanize their pronunciation. I do, however, know some with regional accents who pronounce the vowels differently.

In BrE, you're more likely to see Americanisation in things like stress than sounds. If you take a noun like resource- the BrE stress gives two possibilities. The one that is the same as the US is becoming more and more common.
