So I am not surprising anyone who knows Cambridge Street to admit that it is a little steep. What I didn't realise is that Cambridge Street's steepness would be newsworthy. The below article from the Sydney Sunday Times of 6 January 1929 relates how the Managing Director of Studebaker took out the journo to show him how the car handled some of the well known steepest hills in Sydney.
It looks like Arden Street in Coogee was the big one back in the day but Cambridge and Cascade street represented Paddington. The Studebaker climbed Cambridge Street "easily from both approaches"!
