That was expensive enough to get my attention, and this is why I bought a Freighter so that I could do the hauling myself. A freighter is required not only for the input materials (which have a huge volume), but also for the output commodities that are shipped to a trade hub for sale. A T1 industrial is capable of doing this, but the value of the goods is high enough that it makes the likelihood of a suicide gank very high. A freighter on the other hand has enough EHP to haul 1B isk worth of cargo without attracting attention from suicide gankers.

To get the answer, consider it in a different way. Imagine that you could invest 1.2B isk in an asset that allows you to a few buttons and make 10-20M isk in 1-2 hours, completely passively. This is actually pretty decent income for the effort & time required, and this is why hauling exists as a career. Red Frog would NOT be charging such low prices if freighters couldn't be auto-piloted while AFK! I guarantee you that the vast majority of their pilots are auto-piloting right now.
Red Frog also insures their own pilots from loss, and since it is impossible to enforce a rule against auto-piloting, they must have determined that the risk of a suicide gank is very low. They make the risk so small by allowing a maximum collateral of 1B isk on all courier contracts, effectively preventing their ships from becoming loot pinatas. Conclusion: if you value your time at all, you will haul your goods AFK, and you will not carry more than 1B in cargo.
