Injecting a dummy payload into an eccentric helicentric orbit which periodically crosses' Mars' orbit /= a Mars mission. The complexity and relevance to future human presence on Mars isn't close

(Though tbf the choice of launch vehicle isn't that relevant to whether the ESCAPADE mission succeeds, and missions involving Mars flybys like Hera which are lot more serious than the Tesla one have been launched on SpaceX rockets)

Nice, the wording of "smashed it". Because, the point of getting to Mars or Mars orbit is that you need rocket burns to insert and to land on Mars. Getting to places in space is a delta-V game and paying only half your delta-V costs doesn't count because it doesn't work.
