I start off in my neighborhood by coasting in neutral as much as possible. Even with cold start higher fuel consumption I see the MPG reading stabilize and even climb when I am coasting, so for my Fiesta coasting in neutral works even from a cold start. I can usually recover the average mileage within 4 miles of initial cold start, even though I am getting on a 55 MPH highway and climbing a 10 foot vertical just getting out of my 90 foot driveway.
