Apparently there was a thread on here recently about mums taking their kids to the doctors in a taxi without a car seat. I've had a similar experience before when I've ordered a taxi to pick up older kids that I've been babysitting, requested a car seat for DD and it's turned up without one. Surely a taxi is just as likely to have a car crash as any other car? It wouldn't cost that much for taxi stations to keep a couple of seats in case they are requested.
