But when the default is coasting, you learn to accelerate less and then coast and then use some regen to slow to a stop.
Yes, if you are in areas where this works, but if you live in areas with stop and go traffic, you have to come to a stop virtually every time you slow down anyway, so coasting does no good in that circumstance, as you still would not have momentum to get going again.
I have been ecodriving for at least 10 years, and I can assure you that coasting is better - in particular - in stop and go conditions. You accelerate LESS (that you would otherwise) and then you coast. It becomes a challenge to never stop, or use the brakes. And if you look at what we have learned from traffic studies, this kind of driving actually reduces traffic.
Jackrabbit starts and abrupt stops make traffic worse, and they use a lot of energy.
Regen can NEVER regain everything you invest in getting the car moving, and so when you keep rolling, even just barely, you save energy.
