I have Rivian R1T telemetry pushed to ABRP, including speed. However, after a trip that was mostly highway driving it will show: (image attached). The actual API calls were like: https://api.iternio.com/1/tlm/send?api_key=XXXXX &token=XXXXXtlm={"utc":1710275749,"soc":37.900002,"lat":30.3955517,"lon":-97.8632889,"speed":109.2636,"ischarging":false,"isdcfc":false,"isparked":false,"odometer":21691.70208547078,"estbattery_range":196.99951035950085}
I drove about 50km, most of it on the highway. I would expect ABRP to recognize it as non "Low Speed".

Also, it calculated the "Calibrated reference consumption" as 3 miles per kwh - in reality, it was ~2.3.

Something is wrong here …
