Yesterday we were on our way home from a visit to see our daughter in North Texas. We charged the ID.4 to 100% before we left. After 122 miles we stopped at an Electrify America station on I-35 in Bellmead, TX. Again we charged to 100% (yes, I know about the 80% charge and do except on this trip). When the charge was complete the range and ABRP showed we would arrive home with a 40 mile cushion. About 50 miles or so farther south TXDOT decided to close two of the three southbound lanes for some repair work. We were in a three mile stop and go traffic jam for almost an hour. During this time I was watching the range meter as it slowly increased! Eventually after two different stop and go rush hour jams we arrived home with 71 miles remaining! I was flabbergasted.
