First, keep in mind that they actually do know how to pilot well, because they can thread Command to 12 and even defaulting, that's 13 dice (including the hot-sim bonus), which is generally plenty. Second, note that Machine sprites are excellent pilots. The Info Savant has Pilot Aircraft and Anthroform at 1 because you can't default on those.
If they want to squeeze out a few more dice, one option is to cut the Electronics skill group up, and instead take Software 4, Computer 1. Computer is not too important to be amazing at - not being able to roll at all on the checks that are Computer + Something is bad, but there aren't many that are actually hard and you can always thread. Both of them suck at Hardware anyways, and you can make Sprites do Data Search for you (actually, they are generally vastly better at it than you). That frees up 20 bp which is enough for more piloting skills, and is probably what I would do. Another option is to steal from Edge and/or Willpower (I wouldn't go below 2 willpower, though, as that will probably pull GM aggro).
