For Testing, not sure if there's a better way to do it but here's what I did that worked for me:
I used Debug->location->Freeway Drive Then once the speed was greater than 10.0 mph, I set a nearby Location in Debug->location->Custom Location
For eg: Apple HQ 37.331789, -122.029620 Washington Square Park 37.8009, -122.4100
Ocean 37, 122 (shows up as unknown location on the trip logger table)
