If it were me, I'd rush home on taxi.
If her water has not broken yet, I'd rush her to the hospital on
taxi.
If her water has already broken, I'd call for a non-emergency
ambulance. Call me kiasu, but I'd rather have her give birth in an
ambulance than a taxi.
After all, should emergency complications set in, at least a
couple of paramedics are better than a taxi uncle in handling the
situation....
whatever it is, no one will ever let the guy live this down
me? i'd already have a plan in place.. a route, who to call, who
to activate.. all that...
