Instead of asking why the Department of Agriculture has x number of vehicles, we should be asking why the hell Department of Agriculture has offices in almost every US county, agricultural, urban, desert, lake. Why is there Department of _______________ (fill in the blank)? But of course that'll never happen; we got here incrementally and we might get out of here incrementally too. Unfortunately, you cannot eliminate a government agency incrementally. What to do?
Now, how many of the total employees in a government agency are allowed TO USE THE GOVERNMENT VEHICLE? Probably about 10%.
So, now the figures change a little. More like 10 cars for every 2.7 authorized vehicle users.
