Of course you are welcome to be annoyed by whatever you want but I think I kind of agree with this design... Regardless of what state the car is in, you always know that if you push that button, the car should now be in park. If you're a dum dum like most of us, and you forget whether you've done it already or not, you don't need to check the dash or anything to decide whether to push it or not, you can just do it. It's like saving twice in a Pokemon game. I like that it's two distinct gestures, but compressed down into one mechanism.

However, I'm not sure I like that it's push to engage and pull to disengage. In my car I'm pretty sure it's pull to engage and push to disengage, which reminds me of the old lever style of parking brake.
