Maybe, just maybe, this apparent paradox cannot be resolved by solely analyzing what happens in space, but in spacetime. Tomorrow I will make an effort to fully understand your spacetime diagrams and see if they shed any light on this issue. The clue might be the fact that in relativity, ds^2 is frame invariant. And FWIW, I haven't seen any convincing arguments based solely on the frame non-invariance of simultaneity. It's often claimed this non-invariance solves the problem, but detailed proofs are woefully lacking. AG
Look at the two events (4-points) marked with little triangles at the front and rear of the car. The spacetime interval between these events is invariant.
