This was one trip where the probability of either forgetting it or intentionally not taking it (since the trip didn't involve a lot of charging stops or, say, going to a rental house where I knew I'd have to charge) would be high. I've certainly forgotten to take certain items in the scramble to get out the door before a trip, especially when it involves transportation that has fixed times (like airline travel) and being just 5 minutes late can mean missing a flight. And my point is, you cannot forget something if it's always in the car to begin with.
