Ola Cabs / Ani Technologies — artificial scarcity of cabs

I can see many cabs around on the map but when i book, it shows no cabs and an advertisement flashes that says to buy ola select. I have heard from many that as soon as you go for select, you can find a cab. This is strategy to make people go for select. Ihad been trying to book a cab for about half an hour but could not get any but the cabs that i could see on the map, remained unmoved. So there were notmuch bookings for them too.

Ps: make cabs availability more genuine.
