Yeah likewise - I had it on my build then tried it in my old man's 5GT. Scared the shit out of me! I'm not a good passenger at the best of times because I always feel I see things before the driver and everyone else seems slow to react. But you can get over that and trust someone since you know them and they have self-preservation at the forefront of their mind. When a computer doesn't react when you would ... fuck that.
I took it off my build and added the advanced parking pack instead. I can handle a computer parking - that looks like fun
