The weight of the vehicle is probably a significant factor here. I have a very small and lightweight car. When I coast in gear I lose a lot of speed because there's not much mass moving the car forward and countering the engine drag. I would have to pulse very often to get my speed back up with would nullify the benefit of coasting in gear. Without a doubt I get better MPG coasting in neutral as much as possible compared to always keeping the car in gear. I only coast in gear when I need to lose speed.
Perhaps with vehicles that are a few hundred pounds heavier than mine coasting in gear makes more sense.
The safety concerns in the article are laughable.
