Glad she's okay. Not much to do in such a situation, other than ignoring the idiots. If they escalate, deal with that. If it's possible to evade without breaking into a "run" (ie, prompting the lion to give chase), great. She was armed, which afforded some options if it came to that. On a highway, it's tough as there are limited options. Stopping might have ended with them approaching the vehicle. Tearing off at 100+ mph almost assuredly would have resulted in a chase, possibly a crash. Can't "lash out" at them by shooting them to get them to go away. Seems to me like she did just fine, doing about all one can do when assaulted in that spot.
