There are a number of services that promotes itself as an alternative to taxi. From our son, JJ and I learned of Lyft which his company recommends over the more popular Uber which has had some personal safety issues for their female passengers.
I find it exciting to learn something new. After signing up for the program, I followed their simple online instruction to download their app. J.J. and I used their service twice. Both times, we were given the fare estimate, which was accurate, name and the photo of the driver, make of the automobile and when we could expect to be picked up. An average of 5 minutes from the time of request was excellent.
All transaction is processed online and charges paid via credit card. This avoids carrying cash. You are asked to rate your experience ranging from friendliness of the driver, cleanliness of the car to riding comfort.
If you have not yet tried Lyft, I highly recommended their service.
