as a former yard shunter I often wondered if it ever did, many the night i've been thrown the keys to reverse a container truck into our shed, the most notable was a guy who had been driving artics 20 yrs, couldn't back into our loading bay, after numerous attempts he gave me the keys and in it went, (it was the same manoeuvre I did when being tested).
for the record i learned on a volvo FL10 4 wheel unit, it was great. could put it anywhere ,all our trailers were curtain siders
