In the most likely scenario that the trunk is never damaged in an accident then at some point you are left with a very expensive carbon trunk lid with an embedded battery that no longer holds a charge.

"When critics of passenger-rail subsidies, such as Randal O’Toole of the Cato Institute, suggest that the highway costs are mostly covered by the gas tax, Lind counters with figures from a 2008 Federal Highway Administration paper: the FHA reports that highway user fees, including gas taxes, only cover 51 percent of costs. By contrast, Amtrak in 2010 covered 67 percent of its operating costs from ticket fares and other revenue."
That's BS. First, Amtrak's "Operating costs" are all inclusive, while the FHA's, or indeed all government highway spending, represent only a small fraction of the operational cost of the highway system. Add in a large part of the US auto industry (sales, parts and service, insurance, fuel, etc) and you will get a more accurate picture of the "operational costs" of the highway system.
Or simply compare the federal costs vs revenue by mode of transportation per passenger. Which is something the Bureau of Transportation Statistics did in 2004: http://www.bts.gov/publications/federal_subsidies_to_passenger_transportation/pdf/entire.pdf
"On average, highway users paid $1.91 per thousand passenger-miles to the federal government over their highway allocated cost during 1990-2002"
"Passenger rail received the largest subsidy per thousand passenger-miles, averaging $186.35 per thousand passenger-miles during."
In other words, if a highway user and a rail user both travel 1000 miles, the feds earn $2 from the highway user while they spend $186 on the rail user.
