Yoga mats on the wall are a great idea!
Unfortunately, they won't work for me because I have lifts in my garages. The GT goes on the bottom, but man it's close to the lift's (Autostacker scissors-type hydraulic) giant steel beams on each side as I c-a-r-e-f-u-l-l-y back it in. About 2 inches clearance each side.
My wife refuses to spot me, or have anything to do with helping me park it. Occasionally, a buddy will be there to help. The car is almost exactly as wide as my Ferrari F8 and my previous 812 Superfast, so I'm getting pretty good with slow backing while holding the steering wheel perfectly straight.
I will eventually want to install rear cameras on the GT. The older I get, the less flexible/twistable/contortionable I become.
BTW: Now that I've owned my GT for about 6 months, I only bonk my head on the door about half the time when getting out, in the very tight confines.
