Very good stuff - because some cab companies won't even take a sick dog to the vet (no matter how much polythene sheeting/hard cash bribery is offered), and if things start getting sticky at 3am on a weekday, or halfway through the working day, friends with cars aren't that much help. A lot of women go into labour without anyone present to drive them about as well - woman whose husbands are in the forces, single mums, widows, all sorts, so making life hell for anyone lacking their own car and/or driver just doesn't make sense.
