———————————————————————————
While traveling this past weekend along I-95 between Washington, DC and Richmond, VA (admittedly a stretch that can get very backed up), ABRP's predictions with live traffic enabled were horribly inaccurate, which resulted in some very poor routings, and made it unusable to truly explore alternates.
For example, on a particular stretch of 38 miles, ABRP was predicting 2 hours and 54 minutes, while the car's nav was predicting 46 minutes. The actual time was 50 minutes.
A few days prior, in the same vicinity (but going the other direction) I tried to select an alternative charging stop only to be told it would add 3 hours to my trip, which was of course false.
Turning off live data brought the trip estimates back to reality, but as I said, this section of road does get backed up, so disabling it entirely was not preferable. If the problem was an issue with the live traffic, there is something seriously wrong with its data/calculations.
