Cool, I learned about abstreet the other day from HN! Thanks for the feedback. These days I run everything geospatial in docker containers, the dependencies in geo are tricky. Interesting about the memory/caching issues. I was going to suggest rasterio which I use for batch queries in https://github.com/ajnisbet/opentopodata https://github.com/ajnisbet/opentopodata and comes bundled with its own gdal binary, but looks like you're already using that. I've also used zarr+tifffile for geotiffs in particular, it's faster and avoids a lot of gdal's warts, but you still need something like rasterio to read the geospatial metadata and handle projections.
