So, traffic keeps flowing, so that means less braking, which means less accelerating, less gas and less pollution, less time wasted, and that partly accounts for Europe's better efficiency than we have in the United States.
Deci, traficul e fluent, ceea ce inseamna mai putina franare, inseamna mai putina accelerare, mai putin combustibil si mai putina poluare, mai putin timp pierdut, si asta explica in parte eficienta mai ridicata din Europa decat cea din Statele Unite.
