I feel bad for her. She's probably not dumb, but maybe just desperate and didn't have a compressor. She's clearly on her way somewhere in that dress, and just found out she has a flat and now she's late. Maybe figured she could just get enough air in there to make it to the gas station.
An actual dumb person would just drive on the flat. I've seen several women do that.
This girl is trying to solve her problem with the tools she has available.
