I live in an apartment building with chargers in the underground carpark, so that's where I usually charge. It's cheaper than public chargers, but not quite as cheap as a home one.
Having said that, fast charging is still cheaper than running an ICE, as I mentioned in the parent comment.
I don't think we can universally say that fast charging is still cheaper than ICE, this statement will not apply everywhere in the world. In most EU countries I've been to or lived in, fast charging was more expensive than driving an ICE car with an economy engine. The cost of public charging in my home country for example equals to a fuel consumption of 6.5L/100km in cost, while an economy ICE car consumes less than that.
