Another benefit that I know BMW has (and probably others too?) is that I can press-and-hold the unlock button as I approach the car and the windows roll down. Keep holding, and the sunroof opens. In the summer, it's a nice way to cool off the scorching-hot sun-baked interior before getting in.
This isn't an attack against cars that you have to press a button on the remote to unlock the car. It's an attack on the cars/remotes that are just near each other and unlock/start.
The simple solution: Just go back to pressing a button to unlock and putting the key in the ignition.
If the manufacturer really wants to keep the feature, then they could switch to those keys that flip out like Fiat has and just turn off the near-unlock functionality on the remote when the key is folded in.
