Often wondered the same, in nyc the cabs offer a check in with app (Arro) which takes care of payment (pre registered cc) permitting the rider to just exit the taxi at the end of the journey. It certainly could be better, unfortunately the app devs are fairly unresponsive .. perplexed why this is not funded more

Uber's software runs worldwide: $1m of developer time for Uber has a much wider impact and reach compared to spending $1m on developer time for Arro, which has a much smaller reach and no guarantees of an RoI.
