But bumps "beat the daylights" out of the motor? (Score 2, Informative)

A Oct 2 article in the New York Times about e-Traction included a countering opinion:

But plenty of technological and economic hurdles must be overcome before such motors gain widespread use in transportation. "It is the future," said James Worden, founder and chief executive of Solectria, a company in Woburn, Mass., that has produced drivetrains for more than 100 hybrid electric buses. "Whether it is 10 years out, 20 years out or 30 years out."

Yet Mr. Worden of Solectria said that one drawback in the bus design was that the electronics in the motor were in direct contact with the road, not protected like the rest of the bus is by shock absorbers. If the tire hits a bump, he said, "it beats the living daylights out of any motor or electronics."
