Getting close to profitable makes me think the 2-4 stall sites are probably very busy a lot of the time with consequent queuing.
I do not begrudge them making money but as a consumer, my top desires would be little or no queuing and fast speed plus high reliability.
Queued for 12mins at SC Exeter on the weekend and Evie had 50% out of action and the other ones fully utilized. I did not go over to view the queue but undoubtedly there would have been one. I'm off to Canberra tomorrow and at the time I would arrive in Exeter, there was queuing of about 5mins. However, amazingly, all 8 Evies available at the moment!
Things are starting to hot up with charging and I suspect that queuing is going to worsen before it improves.
