———————————————————————————
I was researching a trip from Mountain View, CA to Whitefish, MT. This is a drive I've done a few times in an ICE as well as my Model 3, so, I'm familiar with it. I was getting estimates of 53 hours in a Bolt (daughter's car), which seemed really high for this route. Then I changed the car to a Lucid Air (my current car) and while the charge stops and charge times came down as expected, the total driving time did not make sense per my experience. I dug a bit deeper and each segment is off by a factor of ~2.2x. Google Maps has this drive down at 19 hours and 11 minutes. My routing in the Air has the total trip time at 45 hours, 54 minutes with 3 charge stops and 1 hour 10 minutes of charging. The problem seems to be the segments. For example from my home to the first charge stop is 239 miles and the estimated driving time is 9 hours 9 minutes. Google maps puts that same route at 3 hours 46 minutes.

Any suggestions?
