I of course can't state sources for commercial reasons but I believe NatEx have put out more routes to contractors and companies who don't already run NatEx have put in bids so if new firms can be onboarded, there is plenty of potential for expansion.
In NatEx case, maybe if they trusted their drivers more, people would be happier working there. The stupid thing that looks at where your eyes are looking so if you look at a mirror too long, it shouts at you. Doing the smallest thing wrong and you're removed off the network, not just for that one firm, banned off the network from all firms so even if you change operators, you still can't work NatEx. If NatEx want to be so draconian with their practises, it will bite them on the behind. Interestingly one firm which never got the new tech was Selwyns but for some bizzare reason, they keep throwing money at them. Selwyns can't run the services properly and often most of NatEx main advertising features, don't come standard on Selwyns. Wifi is often not working and if Wifi does work, VUER or whatever it is called, doesn't work. Buses are often in a state as well internally. Thank goodness for bustimes showing us who is running each trip as I now avoid any Selwyns trip.
