But this alone doesn't prove that the car fitting and not fitting in respective frames does not occur simultaneously. Thus, more information is required to prove there's no paradox. When you claim simultaneity is not objective, I assume you mean it's frame dependent. Nonetheless, it can be calculated for the conditions defining this problem. AG I assume the calculation requires using the Lorentz time transformation to get the event times in the car's frame, assuming we know it in the garage frame.
