Traffic truisms
Some of the points made in Tom Vanderbilt's "Traffic":
More accidents happen on rural roads than urban streets.
Most accidents happen on dry, clear days.
Many road signs and signals are useless, unnecessary, and not even noticed by drivers.
"Rubbernecking" at accidents causes more delays than the accidents themselves, and often causes more accidents.
Even in heavy traffic, driving to work is usually faster than taking public transportation.
Rotaries are safer than ordinary intersections.
More city pedestrians are killed in crosswalks than when they jaywalk.
