I think it is a great idea. I've been riding for 60 years now, and many a time I would have loved having something like that. My old Harley WL had a servi-car transmission with a reverse gear. that was fun to play with even if I never really needed to use it. However, I switched from riding big inch Harleys that I customized and started customizing them back in the 60's, I now ride my '95 FLHTCUI which I have put over 150,ooo miles on and I'm not getting any younger, no matter how much I want, something like that would be a fantastic item to have for when it would be needed. I have not ever had the pleasure of not being able to get out of where I parked, but several times, ok...many times, I wished I had some "help"...LOL
