Description: When planning a route from Ocean City, MD to Annapolis, MD, the web site tells the user to take an unnecessary 188 mile path, when a 108 mile path exists. Interestingly, when the trip is reversed (from Annapolis, MD to Ocean City, MD), the website recommends the shorter 108 mile path. Type: webpage Link to Plan: https://abetterrouteplanner.com/?plan_uuid=84bbe50d-cd4d-4755-8f02-603695e3e83b Replication Steps: Using link above in either desktop versions of Chrome or Firefox, you'll see the longer and unnecessary 188 mile path. Next, reverse your starting and end points and calculate the route. You'll then see the shorter 108 mile path.
When playing around with the site, I stumbled across this results discrepancy. Same starting point, destination point, settings, etc., the only change is a 2021 Tesla Model 3 SR+ vs a 2018-2020 Tesla Model 3 Mid-Range (18" Aero). The EPA range estimate is 263 miles vs 260-264 respectively. The 2018 Mid-Range had the only 260 mile EPA estimate. The results discrepancy is that the 2021 model (263 mile range) requires 3 supercharging stops and the 2018-2020 model (260-264 mile range) takes 2 supercharging stops. On both vehicles, I am modifying these settings from the default: 10% battery degradation, Temperature = 38F, extra weight = 300 lb. Increasing the temperature to 58F doesn't change the results, so I don't think it's a heat pump/winter driving efficiency problem. Reversing the starting point and end point give the same result. 2021 Model (with a heat pump) shows a 1/2 hour longer trip: https://abetterrouteplanner.com/?plan_uuid=e9f4f879-b8ab-47f3-9f8b-aacbf896ab7a 2018-2020 Model (no heat pump), https://abetterrouteplanner.com/?plan_uuid=e205100f-cf61-4dd0-b382-76b1127b171c Is this a bug or is there another reason for the differing results?
