Might be different in other markets, but in my home city picking the best (price, time) ride is not so easy. The time it takes for the car to arrive varies a lot. In all the services available I need to first place the order, then they find the car and after that I get estimate how long it takes to arrive. I can cancel and try another one, but that’s quite inconvenient. Also the time estimates seem to be fairly optimistic. At least on my case this means that I’m not always trying to pick the cheapest option, but instead go with the option that has had good price/performance ratio in the past.
