I felt the same way at first when I bought my MK7 Golf R 3 years ago. After a while I decided to give it a go and ended up permanently leaving it on since. Unlike on the Subaru, pressing on the brake after it engages doesn't disengage the system. That's what bothers me the most about Subaru's implementation. Well that and the fact that you can't actually leave permanently on.Is there a particular reason you want it to always be on? Even though the AVH system is a great feature, you should still be keeping your foot on the brake pedal when stopped.
Even better than that, you can get OBDeleven on your mobile and change everything wirelessly. It's truly amazing the things I can customize on my Golf.A friend has a VW and a copy of cracked software on a laptop. He can change the total feel of the electric power steering and a hundred other parameters.
