opposite direction.

Looks better, a more natural drivers eye view!

A lot of that comes from cropping the excessively wide-angle original
video. On the other hand, if the video is to show what happened in an
accident, you do need as wide an angle as possible.

Very true.

For the majority of TV soap operas, what we once might have described as
"VHS quality" is entirely adequate for viewers to follow the [rather
weak in many cases] plotline|story-arc.

Just because that may be sufficient (of course a text file reading "it's
****, get a life" would be too) doesn't mean that that's what people
actually download. The only content you'll regularly run across at low
resolution and heavily compressed is *old* content.

Would it also have aperture blades?

No. Partly because that's complicated and expensive and moving parts are
likely to break, partly because you don't want the depth of field to
change based on how bright it is. It'll use some combination of fiddling
with exposure time and CCD sensitivity, all of which is purely done in
software, to control brightness.

Yes, that's what I expected.

Nice view of the sky, you need to pan the camera down a bit to see more
of the road.
If I pan it down much, then you get a great view of the bonnet.

Always a problem with those things.

The vertical wide angle is a consequence of the horizontal wide angle.
An alternative would be to letter-box crop the video.
I agree I don't think I've quite got the compromise completely right.

Does it actually have much in the way of adjustment or is it a ratchet
type arrangement where you pick the least worst spot?

There are ratchet points, but somewhat a hostage to the fortune of the
rake of the windscreen.

for me the problem was that, as I had overnight on-street parking, I didn't
want to leave it in place when parked in case some scrote broke in just to
steal the cam, so every time I went out I had to guess the correct place to
put it

And I'd be left will a bill to replace the window that's probably 3 or 4
times the value of the cam

Is that because the originators can't be bothered to compress it
properly, or is it in fact compressed quite a lot, but is *also* very
high definition?

I haven't got a lot of examples, but one is a well known 1280x720 TV
whodunnit show where they get 1.5hrs into 1.2GB

I leave the suction cup and stalk on the windscreen, and the camera just
clips to that. Very reliably/repeatably. If I had to adjust it daily it
would drive me potty.

And said scrote, seeing the suction cup (or even if you did remove it,
the marks left by it, unless you cleaned the screen every time) would
break in looking to see if you'd hidden the camera somewhere.

I don't think I've ever seen a car that appeared to have been broken
into like that. And for £39 of dashcam, would they bother?
