I have a Carver, it's a 3 wheel electric vehicle that tilts as it goes round corners, feels a bit like flying at ground level. I'd like a Head Up Display to show me things like power use/regen, battery level and also an artificial horizon, just because! Getting the data is no problem, I can read the CANbus, but how can I display it? I need a REALLY bright display to reflect off the screen which I can connect to something like a RPi or ESP. Any ideas people?

The brightest screens I can find seem to top out about 1,400 nits. This is the same as my Google Pixel phone on max brightness, so I experimented with reflecting that off the screen. It was great at night, borderline OK in overcast daylight, but not good enough in sunlight, so I need something brighter, like at least 2000nits. It doesn't need high resolution, just brightness. I could use actual LED's for things like a bar graph, and a 7 segment display for text, but ideally I'd like a bit more.

Really, this sort of thing is what I'm aiming for!
