The trouble with mistakes like this is that they get embedded in the public consciousness, are are hard to shift. I read a Canadian rant a few years back explaining how EVs were actually way more expensive per mile than ICEs, I was curious, as I imagined Canada had fairly cheap hydro-electric power. Turned out the cost of a kWh had been taken as $1.50, instead of 15c.
People still believe spinach is a wondrous source of iron, years after a similar mistake was exposed. I sometimes wonder if these "mistakes" are intentional.
Probably not the spinach one.
