NEW ORLEANS, LA (WVUE) - Tailgaters may be defeating their own purpose.
Researchers at the Massachusetts Institute of Technology think tailgaters don't speed up traffic. Instead, they think tailgaters may be to blame for traffic jams that develop without an obvious cause.
They found traffic moves better when drivers work to control space in front of them and behind them. They say that reduces fluctuations in speed among all cars. They blame fluctuations in speed among cars for some backups.
