Boston Parking Meters: Three Year Test Was Success, Let's Start All Over

Today's Boston Globe reports: For parking, a choice of coins or plastic, Test program puts credit card readers on some prime downtown meters:

City officials decided to launch the pilot program following the success of the multispace meters offering credit card payment on Newbury and Boylston streets in the Back Bay and in the Bulfinch Triangle downtown, which were put in place three years ago, according to Transportation Commissioner Thomas J. Tinlin....

He said officials will have to see how the meters respond to the full range of New England’s punishing weather before deciding whether to proceed from the free pilot program — with materials provided by the San Diego-based IPS Group Inc. — to a permanent program, which would be put out to bid.

Why would you need to test a NEW system, after "the success of the multispace meters"?

That's not right.
