The idea of combing trips under 15mins is great. But what about adding a point to the trip if you park the vehicle and and not turn it off. This is good for people that have to track there routes and milage but can not turn the vehicle off. Like me sometimes I have to pick people up and my vehicle compute does not change its state until I am home and off the road; so all pickups and drop-offs run together. I was thinking making the app and adapter read the parking as a change-in-state after about 40-60 sec.
