[X] Beat her up in the car park outside. It's dark, mostly empty, and even if someone notices you'll have time to run. On the other hand, she might manage to get into her car and escape.
I'm not a fan of slashing her tires. Mechanically, I'm not a fan of taking mystery box choices with unspecified bonuses down the line over choices that will get the job done. And narratively, I think it complicates the situation too much. What happens if she crashes her car? Or if she manages to make it home with the slashed tires? Or if the thugs lose her before she has to pull over? Or if the tow truck doesn't come and the poor old lady dies from exposure and lack of medical attention on a too quiet road? Or in the opposite case, she has to stop in a busy area, or stops in at a nearby house to use the phone, which adds witnesses and complications and all this took me a few minutes to think up.
So I'm taking the option of beating her up in the car park. It has reasonable odds of success, and popular support. I seriously considered shooting her to control the situation further, but realistically her dying is one of the worse outcomes for the scenario.
[X] You Don't See Me Rollin', You Hatin'.
I have to wonder how three dice rolls would work. What happens if one comes up a failure and another comes up as a success with a complication. Which would be considered 'better".
