I think Lexus was the first to offer this option a year or two ago.
I think its a great idea but as a skeptic I just have all these ideas running through my mind as to what can go wrong. Sort of like your thoughts on hybrids
You have to remember that I helped write Murphy's law

Like you, I have never had problems parking. Try a 48' trailer, well. now they can be up to 53' (yeah, they have tandems also but you can't back those up.) I have seen road jockeys burn out clutches trying to back in a trailer.
These road jockeys can get a rig on the road and point it in the right direction but once they hit the city streets many of them are lost.

BTW contrary to popular belief, the shorter the trailer the more difficult to back in, it's like a U-haul on the back of your car.
Yeah, I did that for 22 years with SYSCO foods don't remind me
Now if they can only get a trailer to do that, then you have something.

Most of all, enjoy the new car, enjoy the toys and most of all get the hell out of the front seat and let your wife drive it.
After all, it was for her wasn't it. Seems she is the only one that hasn't touched it yet
