Generally speaking, having cars get behind a slow driver tends to save fuel for everyone. Maybe the drivers are annoyed by the slow driver, but that driver is certainly not hurting their economy.
In many cases, eco-drivers will greatly improve the economy of tens, or even hundreds of cars in a traffic jam by moving at the average rate of traffic, rather than accelerating and braking. Cars behind them end up doing the same thing, and the gas savings are multiplied.
