Just a Gwai Lo fun within prescribed limits [?]

As some people know, I've been interested in the new fleet of Nova Buses purchased by TransLink, which have an unusual single seat behind the driver and seats in the back that face backwards. I like the wide entrance at the front, but most drivers seem to only open one of the doors, negating the advantage. I've read somewhere that drivers prefer how the Nova Bus handles compared to New Flyers (and I read in that same piece that it's especially true of icy conditions, but they've only recently come into service, and cold weather doesn't start for a few months). Today comes news that one of the wheels came loose and almost came off while near Broadway and Kensington in Burnaby. This was likely during the 134 route between Brentwood and Lougheed malls, as that's the only route that takes those streets.
