But compared to the US home charging via a mains outlet is much more viable because it's 240v vs 110v. If you plug you car overnight you'll typically have enough charge to last you the next day.
Almost everyone I know with an EV charging at home just reused the 240v dryer socket to avoid paying for a dedicated fast charger. It's often cheaper too to have an electrician fit a new 240v socket instead of the dedicated charger as well.
Home chargers with dedicated sockets is three phase 400v actually over here in the EU and every single home, and even relatively new apartments have that because of induction stoves.
Three phase power is definitely not 100% in the EU. Not even in Germany, though adoption does tend to be higher than neighboring countries.
And FWIW, I find that my induction cooktop works wonderfully on plain old 240V 40A, so I do not think it is a requirement to get three-phase for that ;-).
The US is 240V. We split it into two 120V legs for some sockets, and not for others. Some people do choose to get by on 120V, true, but they are the minority. Usually people who do not drive often.
Most? You mean all. 240V [0] as been the standard in the US basically since electrification started in the late 19th century. 120V has for all practical purposes never been a thing, it has always been an artifact of split-phase 240V. A deliberate choice to offer two voltages to every consumer.
[0] Okay, technically 240V did not become official until around 1967, but the split-phase design was there from the beginning. They capped it at 240V to stop the creeping up that had been going on in the earlier part of the century. This is why you still have a lot of people (not all of them old enough to have been alive in 1967, oddly enough) that refer to 240V as 220.
Sure, but that is the exception proving the rule. Not quite urban legend, you can find people on mikeholt.com who have actually seen one in the wild. Usually because of some shenanigans the local power company pulled to directly connect more houses by giving each one a phase of a three-phase feed.
