You seem to be missing the point entirely. The in-block roads are for when you have something to do in the block, which is why you can't cross a block through them (they loop and send you back the way you came from). You arrive, you do your thing and you leave. The entire block is pedestrian space, which is why the speed limit is pedestrian range.
> maybe let the cars go a little faster (10 km/h is rather unbearably slow slow).
1. that would defeat the entire point of superblocks by still having fast vehicles within them
2. at 400m long, in-block loops can be traversed entirely in 2mn, since you've got something to do there (otherwise you'd go around the superblock) that seems perfectly fine.
