Well Cardiff Queen Street, which has been pedestrianised for at least 40 years was last updated August 2024

Yes, it hasn't gone unnoticed that there are pedestrian areas on Streetview, but ours isn't one of them, apparently. I could have sworn our shopping precinct was on Streetview too, but if so, it isn't any more. Perhaps it comes down to whether someone is willing to pay for it. The interior of a hotel I stayed at on Corfu used to be on Streetivew once, but it isn't now, so I assume the owners decided it wasn't worth the money.

The etymology of helicopter doesn't break it down into heli- and -copter. It breaks it down into helico- (spiral as in helix) and -pter (wing, as in pterodactyl)

The English word helicopter is adapted from the French word hélicoptère, coined by Gustave Ponton d'Amécourt in 1861, which originates from the Greek helix (ἕλιξ), genitive helikos (ἕλῐκος), "helix, spiral, whirl, convolution"[2] and pteron (πτερόν) "wing". https://en.wikipedia.org/wiki/Helicopter

And in modern French, helice means propeller.

The reason sodium ion batteries traditionally had low capacity seeminly WAS due to massive capacity loss in the first few cycles.
Catl has solved that issue by using a sodiated cathode. The new batteries thus match LFP for capacity.
Whilst NMC currently surpasses this by 50%+, long term, I think risk assessments will result in sodium batteries dominating for general home and vehicle use.

Hmmm
When I was in my final year at University I did several things to help develop Sodium batteries
mostly in terms of isolating the crystal that develop inside so they could work out how they occur and how to stop it happening

It involved a lot of experiments using liquid Sodium - my partner (female) refused to get involved in that bit so I did it and she kept the notes and results
That was a long time ago!

I wonder if it is much the same scenario that now gives the batteries an incredible 10,000 cycle capacity.
Amazing considering how immature the technology is.

I am just doing a cryptic crossword and one clue has a cycling theme. The answer was something that was new to me...

Garment for cyclists? (5-7)

Not exactly a new term. This excerpt from Tom Waits' Heartattack and Vine from 1980:
See that little Jersey girl in the see-through top
With the *****-******* sucking on a soda pop

It has probably been used in the sense of the answer for well over a century but I had never seen it used that way. I did a Google search just now and found them advertised for sale in lots of places.

That makes it look really rude

Princess Diana (or Lady as she was then) used to wear them. She looked like a new romantic.
