This bozo pulls $7.50 out of his #$@#$ and bases his remaining arguement on it. What a moron.
You should'nt even address an arguement based on a false premise. Go straight for the premise.
Because transponder technology is in its infancy, there are no reliable cost accounting methodologies for calculating a reasonable per mile cost, not to mention factoring in congestion pricing, improvements and law enforcement aspects.
Doing a literature search on the subject put the author in a difficult position. Oregon, for example, is proposing to change a penny per mile via transponder to be collected at the pump. London is proposing $2.30 per mile to be collected via transponder, after converting metric to English units and pounds to dollars. Singapore has a mature transponder system with a full range of pricing, and its costs are in excess of London's proposed charges. Lacking an established model, the author was forced to bend over and pull a number out.
Using numbers in the London (proposed) to Singapore (actual) range, the sum of $7.50 in billed costs for a rush hour commute from Shoreline to downtown Seattle is well within the range of possiblity. And it helps illustrate his point.
