This surprises me, given that almost every country has safer electric plugs than the US. Heat is a function of current and car chargers limit themselves to less than the current the plug is rated for. "Less than" equals 80% in the US.
It might be that the average euro is less aware of continuous draw limitations since there’s so much more power normally (compared to US residential power).
Could also be that for historical reasons you could have a house wired for 10 or 13 A and not be aware if it.
‘Course you can manage that by having the chargers limit themselves to 8A default (or even always), at 1800W that’s a very slow trickle but it’s something, and even if it does not fully cover your commute it spaces out carger stops or helps condition the battery on cold mornings.
