So it's a great way for pure riggers to have deep UE investment in their primary and get advanced support skills in the bargain, but if someone was or is already an advanced pilot or driver, rigging feels pretty bad to invest in because so much of its current powerful gameplay value (until more robot stuff is added) is duplicating the same skill checks without really adding much value if characters can already make them.
I guess the comparison I would make is if a TruSight used Systems knowledge to give characters firearm abilities in the bargain, while providing some cool functionality to guns that firearms users didn't get otherwise.
Now plenty of riggers rely on this chrome now for these support abilities, so I am not suggesting it get removed or anything like that, but I think it would be nice if it provided some benefit to riggers who are (or were already) expert pilots and/or drivers.
So my suggestion is the following, in some future uncertain date when there is dev time to add features:
+ Make the ARIN chrome a generic robot controller; and,
+ Make the vehicle rigging mechanic combine rigging and the relevant vehicle skill for ability rolls, in a similar fashion to how multiple stats are checked on those rolls.
Although additive skill rolls would be super powerful in other instances, the value of extremely high vehicle rolls is pretty low and I don't think there is a great danger of players spending hundreds of UE in both to get huge vehicle skill checks.
These changes would make rigging feel like a much better addition to characters that already have those support skills, and it would make the chrome much more useful in a wider variety of rigging circumstances to all sorts of characters.
