That is quite true, except with the winch you have the full runway length
of rope between winch and glider.
With the Car, you can only start with half that distance from car to
glider.

If OP is at Hobbs, there's no lack of space.
With a payout winch, its possible to drive around the corners
of the huge triangular airfield and keep climbing.
Don't know if anybody that does so with a glider, but I did that
with a hang-glider back when Curt Graham had a hang-glider
operation at Hobbs (kinda weird flying around the corner
on a ground launch).

Payout winch keeps line almost always off the ground,
uses more of available space - anybody doing glider (sailplane)
payout launches these days???
