For the Hard, yes; she's a combat driver. (It appears to be the only Driver line with Hard+1. Hard is a pretty damn powerful stat, as I learned playing Daryl the Muscle who is a bloody fucking runaway freight train who has been described as a "murderous gorilla" by her enemies and a "monster" by her own goddamn employer) so I could see that being the reason--but none of the other playbooks put that kind of premium on Hard. Then again, none of the other playbooks are driving a 3-armour tank with 3-harm close/far area machine guns strapped to the sides that also gives them a +2 on aggro/seize rolls, so that might be a loaded comparison.
The Operator, however, doesn't appear to have anything remotely like that going on. The stat line is kind of boring and doesn't really have anything that seems to be at a premium (just Cool+2 Hard=0 Hot=0 Sharp+1 Weird-1). It couldn't be that it's a line with Sharp+1, as the Operator gets other stat lines with good Sharp and no such premium. It's also not that it gets a penalty to neither Hard nor Hot, as there's an Operator line that actually gets +1 to both of those (and it's the only Operator line that gets a positive Hard, and it doesn't even have a Sharp penalty, just the same Weird penalty 3/4 of the Operator lines do--Cool+2 Hard+1 Hot+1 Sharp=0 Weird-1). I could see balance reasons to put a higher premium on Hard+1 for the Driver, but the Operator line genuinely comes off as in error, unless there's something I'm missing.
