For the uninitiated, Ikarus was a Hungarian bus factory that produced buses to the Eastern block, some of those are probably still running somewhere in Mongolia. The Ikarus 256 was produced between 1974-2002, so in the best case that thing was at least 23 years old.
But even better, someone got to travel on an Ikarus 55 on the same day (1954-1974), which used to be great in their time, but definitely weren’t made for 36C summers, the lack of air conditioning combined with the sunshine roof that used to increase the feel of comfort in 1958 created a living hell for the passengers packed into that rolling museum with barely openable windows.
I’m surprised nobody mentioned jack plugs yet. Basically unchanged since 1877 when it was invented for phone switchboards, roughly as old as safety pins or modern hairpins (give or take a few decades)
