Automation doesn't have a lot to do with size, you can automate SM+10 craft just as easily as SM+4, but an easy way to avoid that sort of distortion is to place a limit on the number of drives large ships can have, so small ships can be faster (by having more drives relative to their size) but aren't more efficient.
