I see this as a great idea. I always have the fob in my jeans money pocket. Which is the ideal size for it and hey - there's never any money in it anyway. My Apple Watch carries all my money these days. 😬 Anyway, why is it a great idea..? Because when you approach the car with the groceries, etc, you just reach forward, press the boot latch button, and Bob's yeruncle, the hatch opens - albeit with a minor lift effort as well. I do not however resent not having a powered opening hatch, as I think just doing what I described is actually easier than risking overbalancing trying to wave your foot somewhere under the rear bumper, but maybe that's just me..?
But the other neat thing is that it does not open the doors, and when you close the hatch, the park light flick, and it locks itself again, and the car is then secure while you return the trolley to the trolley bay, or whatever. It also means that while distracted with dealing with the shopping, no-one can just leap into the vehicle and nick something, even though with the key on you, they will not be able to start it or drive it away. Although even that might be something the clever crims have worked out a workaround for - you never know. Especially when you hear about that USB trick to fire up the ignition. Corrected in later models I believe..?
