I've used Taxi apps, and have called taxis more than I've used Uber/Lyft in the past few years.

But the reason for this is because of surge pricing. The times I want a ride are when everyone else wants a ride, and we're all coming out of the same venue. Taxis offer much more affordable fares, and sometimes will even be parked outside waiting for the people exiting the venue.

Saying no one is using taxis is not true. Few people think to use them, but there are times when it is worth it.
