Just thinking out loud (and being absurd,) what if we took it a step further? What if FSD allowed you to drive onto semi's that were car carriers? Sure it'll be a little bit of a burden on the Semi, but it's not like you're plugging into it to charge while you hitch a ride...maybe it'll even turn into a gig thing. TeslaLyft. You can drive on, hitch a ride, grab a charge and you end up paying a small fee. The truck has to keep going that direction anyway; especially for return/empty legs. Then again..maybe I just want the opportunity to pretend I'm knight rider..
I loooooved Knight Rider as a kid. Episodes are available on CBS All Access so I pulled up my favorites. Wow, that was some horrible acting/scripting/ production. But still cool!
