knn, take MRT home when his wife giving birth?
could not get home in time before wife had to give birth?
actually think about it, if he rushed home by taxi, then rush
the wife to hospital by taxi, the child could have been born in a
taxi 
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....
