traffic congestion

Some of us just want a satnav which tells us how to get from A to B while avoiding traffic congestion. Others, apparently, want a satnav that imitates SpongeBob SquarePants for reasons which, to be frank, are completely beyond me.

After all, I don't live in a pineapple under the sea.

Drivers are spending less time stuck in rush-hour traffic for a second straight year,  as high gas prices and the economic downturn force many Americans to change how they commute.
