The route to Broken Hill needs some priority, but there is a slight issue...
From Cobar to Wilcannia is 261km, which for SR+'s doesn't leave much leeway for wind, bad weather or broken charging hardware.
And looking at Streetview on sections along the stretch, there doesn't seem to be any power lines along the road, so there is little chance even a small "filling station" could be installed between the two towns.
Anyone want to invest in a Solar powered charging station (with batteries) at Noona?
