>>1177333Not a clue. It's like they think they somehow came up with that idea, when euro cities had had steam interurbans since the 1870's, and in america they only became popular with electric traction.
Electric interurbans were very common in Europe as well tho, except they weren't so iconic as the americans as the standards and rolling stock varied more widely.
In Spain to this day the expression "interurban buses" is commonly used.
