Yeah, hauling is a big concern.
Not even just because of time issues. Hi Sec ganking is seriously crazy these days. (I actually think some areas of low sec are safer.) I was moving a mackinaw through hi sec a few weeks ago, on autopilot, and somebody ganked it just to get the T2 modules.
Also if a Triglavian invasion happens and you’re not watching for it.
Getting blown up is very expensive.
