Taxiforsure — Taxiforsure not ready for long travel

My wife is pregnant and we have been using cabs for almost a month now daily. We tried various cab services and for a week we tried TaxiForSure. Problem with TaxiForSure is very few drivers are willing to come if the travel distance is greater than 5 Kms. It was strange to me initially because generally I have seen that cab drivers avoid short distance as the charge will be better for a long/medium distance. I once asked a TaxiForSure for the reason and he said that it is because their commission is directly proportional to the number of pick ups and not on the distance travelled. So they prefer to run many pick ups/drops and it is possible only with shorter distance ride. I think the problem is fundamentally in the TaxiForSure policy. I think cab driver commission should be based on the distance covered instead of number of pick up/drop.
