Ottawa residents lose by being the beta tester and Alstom is the benefactor when they get the many bugs out and sell it to other cities.

I certainly understand that beta technology is a risk (Scarborough RT!) but to say that any new technology is a beta technology is a bit of stretch. Overall, the Confederation Line is a collection of existing technologies, with some implementation problems. There's nothing new about any of it actually, no weird proprietary designs or limitations. When the Alstom LRVs need replacing, we can go to the market and there will be compatible vehicles from multiple manufacturers, all largely standardized.
An LRT with OCS is common the world over with little change in decades. SELTrac is mature technology, and Alstom is a reputable supplier, including experience here in Ottawa. The trains themselves were new, but based off an existing design from a company with a portfolio of these products. When the three consortia were bidding, one chose Alstom, one chose Bombardier and I don't recall the third. Alstom had a modified existing product, Bombardier had a modified existing product. The third option wasn't Siemens, the only company with a proven product in the North American market. Even if it was though, the trains we bought would be unlikely to be identical to anywhere else's.
Trains aren't like cars. Volumes are low enough that there is rarely a fully proven product on the market, and each customer is going to get an iterated design with changes to keep the product current and meet local needs. Someone is always going to be testing the new product or we'd be stuck in the steam era. I understand Jarrett's point, but I feel like it applies better to things like hyperloop, maglev, and other systems where the vehicles are specific to one manufacturer.
