>Have a single child? You need a minivan.
Seems like hyperbole. If anything, the empirical evidence suggests the opposite. You can only fit 2 child seats in a "normal" car, so if you want 3 kids (requiring 3 child seats), you need a minivan. However, minivans are apparently so undesirable that there's a mild contraceptive effect on births, because parents keep their kid count to under 3 to avoid getting a minivan.
