The feeling comes from real world experiences with electric cars, which for 90% of Americans is primarily dealing with Tesla. Stupid door handles, stupid steering wheels, stupid touchscreen based controls. It’s a real complaint, and if it’s coming from Americans it’s primarily complaining from the dominant electric car brand they’ve had experience with, which is an American brand with American made cars.


Almost every American home has 240V coming in, with 2 hot wires with 120V AC exactly 180° out of phase with each other, and a neutral wire that’s supposed to be roughly ground voltage. The standard is to split the 240V into 120V for each circuit at the actual breaker panel, by feeding each normal circuit in the house one hot and one neutral wire. But setting up a particular circuit for 240V service is trivial by using both hot wires.
And the actual distribution grid itself, before it hits the transformer that steps it down to 240V right before actual customer meters, is going to be much, much higher voltage in any country. Higher voltage means less line loss, so power lines use high voltage. That part doesn’t differ significantly between countries.
