Also it was before the advent of mobile phones as we know them now, we would have been flood with calls otherwise with few callers knowing exactly were they were.
Which is why the emergency phones on motorways were once known not as Vodafones, but as Skodafones.....
Although Skodas of today are vastly superior to the wretched things of those days. Not quite as bad as the truly dreadful 'FSO Polonez' though - aka the 'KGB GT'.
