Why would a contract worker be given a car? They are not even employed by the government! Technically they are employed by the employement agency they are contracted through.
I wonder if vehicles own and operated by the military are included in the count. That would greatly skew the numbers I would think.
I think that the argument here is that only the government employees are performing essential functions that also require the use of a car. Everything else (the "non-essential" stuff) has been farmed out to contract employees. Therefore, one should expect a high vehicle to employee ratio.
As I said, I think that this is the argument. I didn't say I was buying it.
