This Adam Something also has a video essay where he trashes battery electric busses as the most ridiculously bad idea ever. At the time of publishing thousands and thousands were already on the road for years in the Netherlands. This guy checks what his audience already thinks on a subject and then makes up arguments to go along with it. Take it with a kilo of salt.
I totally agree in broad strokes about Adam Something. He's an unserious urbanist meme YouTuber essentially. However, battery electric buses are seriously more expensive and a bigger carbon sink than a trolley bus network. But governments don't like to build infrastructure in the west and some people don't like the look of overhead wires. This isn't economically or environmentally efficient but those preferences can…
We even have a city that built a trolley bus network. But it never caught on simply because it has too many drawbacks. It's worse than a BEV bus and worse than a tram but does come with the upfront investment bill.
BEV buses that replace diesel ones are working great.
