Ignore my squawking in this video but check out how my S is parked. My outlet is slightly out of the camera's frame on the left side, a few inches above and to the left of that foam panel stuck to the wall (for door cushion...) The UMC that came with the Model S is plugged into that outlet and then just sort of lays along the ground, or slightly suspended, to where the bikes are hanging up. We used to leave the cable on the bike wheel. (Now, we use the bikes a lot but rarely charge the car in the garage because we've since added a HPWC outside.) There is barely enough space to walk behind the car so you kind of walk halfway back and reach over the car to grab the charge cable off the hanging bike and it semi lays on the ground behind the car/semi suspends in the air.
Long story short, it was long enough to wrap around to the opposite side of the car, even if you pulled it as tight as it would go whereby it was touching the tires/ground.
