What causes Wifi to cellular handoff reason 10?

Fairly sure it's due to device sensing it's in a vehicle with confidence level above 75%, but need to confirm.

User is either biking or driving with confidence level 75% or higher -- When a WiFi call is initiated, Project Fi begins monitoring a user's activity through the use of Android's activity recognition API (ActivityRecognitionResult via TeleActivityRecognitionService). If the service specifies that the user is either biking or driving with a confidence level of 75% or higher (in most cases), Fi will attempt to switch the user from WiFi to cellular.
