Infrastructure needs central backing, that's not exactly controversial. Would you rather each individual company has to fund its own chargers and end up with a patchwork that only works for each brand individually (and probably change over time to not support older models). Thats how the railways initially developed in 19th century Britain and it was a horrible mess of privately owned incompatible gauges.

Can you name a single industry that wasn't created off the back of government investment? This isn't about handing money to private companies, it's about getting the shit we need to comply with the laws that are being set. I'd fully support private industry funding the entire thing but what evidence is there that they'd actually do it? They haven't over the last decade outside of Tesla, so what's going to change that now?
