    Seems if we drive around town, stop and go driving in Prime on battery, the ECO score when we shut off car tends to be in 80s or low 90s. Yet when we drive the interstate on smooth more or less level roads with cruise control on, the scores are high 60s to low 70s. Not a big deal, just seems odd then letting the cruise control "drive" should give a better score than stop and go town roads. Maybe fact ICE gas engine is doing the interstate work instead of town battery enters the calculations.

    Hope everyone had a covid safe Thanksgiving gathering and looking forward to Christmas and New Year.

    Yesterday I got a 99 score on the eco meter. When I turned off the power it showed a different display with a low 70 rating.

    While the eco score do seem to be fairly accurate based on driving style, I’ve definitely seen things I consider odd. Like I’ve come to pretty short stops and gotten “5 bars” while at the same light, done a much more gradual stop and gotten.. 2 (and a lower score).

    Cruise control also seems to yield pretty bad scores, especially on the highway.

    I believe the current eco score resets each complete stop you make. When you turn power off you get your overall grade for the drive.
