There was a production car planned called the Lightyear One [0], originating from a Dutch student team, but if I recall correctly it was quite difficult and expensive to manufacture.
I personally use Skia, in combination with a very thin platform layer. I do use C++ so that might still be a bit too low level, but after having set up everything, the Skia API is really nice for just drawing some text / other primitives onto the screen.
React Native uses Skia under the hood as far as I recall.
That wasn't my intention. The intention was to share the joy of working on a single project for a long time, and holding myself accountable to keep working on this project instead of abandoning it.
