Considering your assertion, or more appropriately your conviction that most traffic fatalities occur away from population centers on highways, I encourage you to check out page 144 and 145 of this report by the National Highway Transportation Safety Administration. Roughly 16% of fatalities occurred on Interstates, Freeways or express ways. Over 60% occurred on roadways classified as less than a principal artery.
If you are so far off on this assertion, should we expect your other assertions to be any more on target.
Perhaps you shouldn't dismiss things so quickly out of hand before you check your facts. Just as you dismiss the 83,000 without really examining its validity. If that number represents the cost of an illegal over time and the average illegal is in the country for 10 yrs (numbers are for example only, not actual data), then it would represent only 8,300 per illegal per year. This would be a value not so easily dismissed.
I am afraid you are demonstrating far more bias than those you would indict for the crime.
My spectulation was that traffic accidents would be more likely fatal if occurring on an expressway/Interstate rather than a local road. That speculation was only that as I said.
There was never any doubt that more accidents occur in the cities but they are generally at a lower rate of speed. It is a truism that more accidents occur close to home.
Rather than "dismiss" anything out of hand I examined what the figure of a trillion per YEAR would mean on a per capita basis and found it to be so unlikely that it dismisses itself. Throwing in your ten year figure is not something that should be in the calculation. Your figure is more believable no matter how you arrived at it however.
