The UK were the first to develop and adopt many things. Being the first adopter, does one no financial favours at all - all the expense, then perhaps development might find an entirely different and incompatible path. EV's will likely be just a temporary blip, to be replaced by something better, and more environmentally friendly.
We developed railways, only to eventually be left way behind, as other countries took advantage of our expensive mistakes, and were able to avoid them.
WHAT???!!!
Britain's power was at it's absolute peak when we gave the world the steam engine! We exported all over the world! Entire countries have largely British rail infrastructure and they paid handsomely for it!
