Wonder how much further you can take it. If you lose a little safety (trains) and take more people off the road, you increase the risk of a train accident. How many people go back to the roads after a train accident? Is the backlash greater (my 0 data thoughts would be that more people would return to the road then just if the train was slow). I heard somewhere that more people died through increased car accidents after 9/11 (forget time span) that would have flown but didn't.
