Lean Angle Gauge?
Is there such a thing? I was thinking it would be nice to have some sort of gauge to let me know how far I was leaning before I scraped the sidecar mounts on the ground (when sidecar is detached).

Attach a video camera pointing at the region in question and film your ride.

Isn't that's what knee pads are for? 
The simplest way to work your lean angle out, would be to supend a small plumb line over the handlebars, & have graduations along the bar to read how far off perpindicular the bike is.
& there's probably a digital sensor that does the same thing.

Believe it or not the plumb line would lean with the bike, the whole principle of cornering is to balance centrifugal force with gravity by moving the centre of mass inwards, if you resolve the forces involved, the vector diagram should produce a line through the centre of the bike down to the contact patch ( assuming your not leaning off of course).
I assume the ones they use for the on screen display in MotoGP use the built in GPS on the bike.

You're absolutely correct about centrifugal acceleration. A plumb line wouldn't do any good.
As for MotoGP, I'd bet a gyroscope would be simpler and better than GPS.

Maybe steal a glance at your brake fluid reservoir?
Measure it later.

If you're turning correctly, your eyes won't be anywhere near your gauge cluster, so what's the point?

Mitsubishi used to have one fitted in the dash pod on their 4wd models.
They were known as WANKLINOMETERS.
