And there is a considerable risk you will be beaten and mugged if you are male and raped if you are female...It is... but you know... you do save some money ;-)
And taking a taxi actually isn't that expensive. A while ago somebody did a study showing that unless you used your car something like at least 5 days a week, it would cost you less over a year to just take a cab. Might not have been 5 days; could have been a little less. But the point was that if you didn't use your car regularly and drove an insignificant distance a week, it would yearly cost you more than just using taxis.
