Consider three vehicles A, B and C moving with non-zero constant speeds and varying angular rotation rates. We know that, with respect to the frame attached to vehicle A, B moves in a straight line path (either approaching or receding). Similarly, with respect to the frame attached to vehicle B, C moves in a straight line path (again, either approaching or receding).
Does this imply that from vehicle A's frame of reference, vehicle C also moves in a straight line path? (This line could be different from the straight line connecting A and B.)
