[talk-au] Fwd: Assistance with ongoing disagreement regarding intersections

[Graeme Fitzpatrick]

Continuing on with that line of thought & looking at the example mentioned
in the other thread:
https://www.openstreetmap.org/edit#map=20/-31.99548/115.99338

How should that left turn from Tonkin Hwy to Hale Rd be mapped?

As a relatively smooth curve the way it is now, or as an abrupt 45° angle
at the physical traffic island eg ___/_|__ ?

Thanks

Graeme
