Yeah, those are some questions a non-jumper might asks. It takes about 6=

Default Parachute Lanyard

Even if you rely on the lanyard, you'll still be spinning like a top. As
soon as you exit the glider, you will be unstable, spinning and tumbling
around. There is a very good chance the lanyard will wrap around you,
perhaps tying you to the glider.

I question whether a first-timer in freefall would have the environmental
acuity to recognize their altitude, especially since he'll be spinning and
tumbling wildly.

Do an AFF or just take the risk.

Default Parachute Lanyard

With a 20ft lanyard, you won't have much time to spin before the chute is
pulled.

With a manual chute (which I use to have on my back), I would pull
immediately after egressing the glider at any altitude I usually fly at
(which is up to 18'000 ft). Especially when the mountains below me have
their tops somewhere between 10'000ft and 14'000ft.
Hitting a mountain slope with 5 m/s while dangling unconsciently below a
parachute may not be the optimum solution. However, hitting it at 200 kph
with my eyes wide open seems to me even worse.

I take emergency parachutes as a tool to survive, not necessarily as a
solution to just walk away.
