Automotive dashcams are pretty decent today and not too expensive.

But, looking over my shoulder, weigh benefit vs. issues.

I am not saying yes or no, what I am saying is run this through SSA and AOPA legal BEFORE jumping up and down too hard.
Let GA aviation legal peeps weigh in first, give us ideas, pluses and minuses.
Let users, weigh in.

Then, and ONLY then, "maybe" involve regulatory/government types.
Think of the comments regarding ADS-B mandate, gliders are currently exempt in most cases. I shudder to think of costs to marginal sites if the FAA said we were no longer exempt in most cases.

Yes, some of us would be safer. Then again, some of that would be because you just lost pilots and clubs/operations.

I am NOT disagreeing.
Yes, it can be fairly cheap per ship.

ADSB is more expensive, but likely to have more positive impact, but still a lot of negative attitude.
Accident investigation is a minor percentage of glider flights.
While nice, and less expensive, please keep regulatory peeps out until aviation legal EXPERTS can weigh I .

What I will say, I would volunteer to send a link to this thread to AOPA Legal. Not only am I a member, but I pay extra for the legal aspect (since I have flown as commercial glider for decades, was CFIG for 8 years, just covering my skinney butt.).
We can see what an aviation legal expert suggests.

HmmmmmK?
