I want to share my experience in Ola cab. I used Ola cab first time from howrah railway station to Kali Mandir in kolkata. Really its more reliable and comfortable. Its started in 2010, before that taxi driver demand more money for less distance . for example If one driver is demand 500 Rs for 10 km then due to union of those taxi drivers, every one demands same money, so you have no option, finally you have to pay more money. Now a days peoples are not facing this types of problems because of Ola cabs. There is no bargaining .
Even this cab is safe for woman and girls in night also, it can be easily traceable.
One more benefit of this cabs is, Metro cities there is parking problem, If you are going to market in metro city you will face the problem in car parking, So Use Ola cab.
Generally before coming Ola cab in India people are bound to go taxi stand and bus stand But now a days where you are, just book Ola cab, at same point Ola cab will pick up you so you not need to go here and there to search taxi.
