I did not smell car exhaust as much as diesel fumes from the Busses!

Capitol Metro uses a special type of diesel fuel that doesn't
smell anything like normal diesel. Soem of the busses are hybrid
electric/diesel as well - they use electricty to get up to speed
and diesel at cruising speeds.

That would be low sulfur diesel fuel. It still stinks and the
particulates are still a problem.

The diesel-electrics sound interesting though.
