I would say that Torrens>Regency Road would be a little unneccessary now, given that they have done all their recent kerb and footpath work, as well as the painted medians now removing right-turn-conflicts. 2+2 lanes would be nice, but difficult.
As for Regency>Grand Junction, I am very happy to see that they have widened the southern section with in conjunction with the construction of the new Bunnings and the intersection for the carpark. IIRC, this only leaves the section between here and the top of the former railyards? One would hope that with the construction of the Coles superstore and the rest of the Churchill Centre (where assumibly, they would add another intersection for carpark access?) they would duplicate the road within this project. Then that will make travel to GJR all on 2+2 lanes, and 2+2 lanes on Cavan Road, getting to Port Wakefiled.

This just seems to be the new thing of late. I don't mind them, obviously they're cheaper than a raised median, but for a 1+1 road (assuming 1+1 is appropriate to capacity) they make right turns easy into properties and businesses easier, which would otherwise require a u-turn, and it also allows cars to pass someone turning left, or to easily pass a bus at a stop.
I can understand your point of view towards pedestraian safety. It does just require a little additional brain usage by the people driving down the road to not just pull into the median at any loaction, but it is significantly safer than crossing a road with no median of any kind.
These are popping up quite frequently in the south, with Aldinga Beach Road, Seaford Road, Commercial Road, just to name a few.
