Instead of conducting an expensive in-house trial which is attracting a miserable 40 to 50 staff members a day - about four a trip - AT could install a Hop card reader in the new shuttles and welcome all-comers.
If demand calls for more mini-buses, then why not? The worst that can happen is that existing services will be forced to compete for customers.
And not just for West Auckland customers. AT's parent body, Auckland Council, is considering a similar superior staff shuttle between its Manukau offices and CBD headquarters. It is planning a 30- minute trip, which is nearly three times as fast as the current 80-minute bus trip and 10 minutes better than the scheduled rail journey.
Again, if the Auckland Council can run such a speedy service, why restrict it to the bureaucrats.
It should be showing the private operators how it's done. Or persuading them that augmenting their existing fleets with smaller, more flexible shuttle services is worth considering.
What is dispiriting about the AT and council shuttle plans is the failure to foresee the public fallout that was inevitable once the trials became public. And that's giving them the benefit of the doubt. They could well have known it would attract great public cynicism and gone ahead anyway.
In defending the shuttle, AT issued a statement saying there would be no dramatic improvements in train travel times until the City Rail Link tunnel was in place.
But that could be a decade away - possibly much longer, given Auckland's chequered record with trains - which is of little consolation to present-day passengers.
Also in the future is the redesigned bus and train network. This revolutionary project links the bus and train routes into one integrated whole, made up of "frequent", "connector", "local" and "peak" services.
We're promised that by 2016 we'll be enjoying more frequent, more connected travel for which you'll just turn up and go at a bus stop, train station or ferry terminal.
But why wait until 2016, when AT and the council are boasting about their ability to provide a rapid and regular service to points west, south and north here and now. The only catch, you have to be an employee to qualify for the superior service.
But if they're not going to share their shuttle buses, I agree with other critics that AT should abandon the $122,000 experiment and discover what it's like to travel on the public bus and trains service.
It continues to amaze me that those making the decisions at AT aren't required to experience the service they're paid to provide for the rest of us.
Then, for example, it wouldn't have taken several years for them to realise that the burgeoning bus service across the harbour bridge was endlessly held up in a small choke point on Customs St heading out of the central city. Finally, a small stretch of bus lane has solved the problem. Sitting in a bus, instead of their cars, they would quickly identify the need for small stretches of peak-hour bus lanes elsewhere.
They would also appreciate the urgent need for a bylaw which makes cars give way to buses pulling out from a bus stop into a long line of traffic - a courtesy commonplace in Sydney and, I'm told, elsewhere in Australia, but not in Auckland.
