On the "Dev" tab of the Companion App, the "Mileage" and "Outside temperature" have very extreme ranges. The "Outside temperature" can be set from -100 to 100 Celsius. Which is never happens in the reality. A range -60 to 60 is more realistic even though still very extreme.
"Mileage" can go to 9M km. Despite this max is not realistic. This range makes it close to impossible to set a reasonable value. Suggest: 1M km max. I think to supporting the record value is OK for us... https://www.guinnessworldrecords.com/world-records/highest-vehicle-mileage
