But Goddard's
estimates are riddled with errors.
General Tax Subsidies.  Goddard says that gas taxes and
motor vehicle fees "cover only about 60 percent of the $53.3
billion that all levels of government spend [on highway
construction and maintenance] each year.  The remaining
$21.3 billion comes from general tax revenues that state and
local governments assess on drivers and nondrivers alike."
Goddard's arithmetic, which is based on 1989 figures, misses
four important points.
First, in 1989 highway user fees spent on highways
totaled $44.3 billion.  That was only $9 billion less than
the $53.3 billion cost of construction and maintenance, not
$21.3 billion as Goddard claims.12  Apparently Goddard got
his value for the difference from a source that he did not
realize had added to the total costs of construction the
costs of police, administration, and debt servicing.  In
other words, he did not acquire construction costs and user
fees from the same data series.  That means that he double
