Hey, I'm trying to throw some actual numbers into the discussion in response to the assertion that trains are more efficient. Perhaps those who want to make that claim can start supporting their own? Give me something to work with here. Rolling resistance is the big issue that usually favours trains. On the other hand, could we design cars with an extra set of wheels or something? |

For long distance/high speed aerodynamics is more important than weight.
