Hi Cathy58!
Age 65 is young! I am 77 and I still drive and drive well too. I am a little nervous in a lot of traffic since you just don't know what the next car to you may do so I drive early in the morning when there is less traffic. My husband is 82 and he drives wonderfully! Plus he can park so well too! It's mainly a personal decision. However, you never know when what or whom you have been relying on may not be available. Also keep in mind that buses and taxi's are often not safe. At least they aren't in Washington State where I live. The buses are full of homeless here and taxi's are often driven by people who are high on drugs!
Pray about it and God will direct you to the right decision!
