Wow - that's actually amazing that the lift mechanism and the driveshaft can support the weight of those behemoths. I like the idea, but I can't see Cadillacs, Lincolns, Jaguars, Mercedes, etc. going back to the continental style of spare tire just so they can have some weird (but badass!👍) parking aid.
That being said, I wonder what would be possible with one installed in both the front AND rear ends... the possibilities would be endless!💡
I just hope someone with time, money, and an old car sees this and gets an idea...
