I have a just-just delivered Cayman S with Comfort Access. Has anyone discovered a trick to reliably have the rear trunk open when placing your hand underneath the spoiler? I end up waving my hand there a couple of times before it opens. I have tried to notice if there is a specific spot to hold your hand or gesture that will reliably work and have not found anything. So I end up making several attempts before it opens. Almost faster to fish the key out of my pocket and use it to pop the trunk. Thoughts?
