What is the best options for tippecanoe to process line string features?

I have a GeoJSON file with a FeatureCollection (more than 300 000 features) of LineStrings. It is a road traffic records. I need to convert it to the MVT format using Tippecanoe. I'm trying to convert the GeoJSON with this params:

tippecanoe data.geojson -pf -pS -zg --detect-shared-borders -o data.mbtiles -f

Then I uploading it to Mapbox account as a tileset and use to render with Mapbox GL JS. And there is a problem - not all the features are visible. Moreover, if if will reconvert the GeoJSON file - then I will get a different result! So - what is the best options to use with tippecanoe to convert all the features (lineStrings) without oversimplification to use it with Mapbox GL JS?

P.S. One more thing which I noticed is that datasets uploaded with Mapbox Studio and then converted to tileset has some info like this: "This layer contains mostly LineStrings", but with my own tilesets converted with the tippecanoe I see a next message: "* No dominant geometry type*"

-ae will auto-increase the maxzoom if features are still being dropped at that zoom level. But when zoomed out it doesn't always look good depending on the type of features (e.g.: mising cadastre doesn't look good)...
