Well, that's why she has the sling and a lined coat, as far as the rifle goes. Eventually, she'll pick up a shotgun for more close-quarters work, but she'd prefer to stay in the car, or better yet hack in from a remote location, and let her drone be her physical presence.
As for the drone, yeah, it was never going to be in the car. More like following in an escort role, like you see cops do with the president's limo. If I had more money, I'd have slapped chameleon coating on the vehicle and the drone. If it is going to be an issue, I can dump the houseboat, and use the money to get a more substantial vehicle that can hide the drone?
