Side note is that I discovered Uber, it's an app on your smart phone. Very clever and worked like a charm. It really depends what area you are requesting a car. On the West Side of Los Angeles there are cars available day and night. The most I've had to wait is 3 to 4 minutes. A whole lot better than taxi cabs. And certainly cheaper.
The price between a Taxi cab and Uber can be half. You do have to sign up and link your PayPal account but money never exchanges. You do not tip and you don't have to worry about having the exact change. You are able to request an estimate on how much it will cost and when you request a car it is there in minutes. Both the driver and the passenger get star ratings and you are able to pick a different driver if you don't like the one you got.
When you request a car you are sent a picture and make & model & the driver with their ratings. If you don't like the car or the driver or the ratings, simply cancel and request again. So far every driver and car I've had has been very satisfactory. Actually better than many cabs I've taken. The cars have to be 3 years old maximum, so you sit in a fairly new car. The driver handles the traffic and you sit back and relax.
I still have a slight limp and minor pain but definitely much much better. Thank you to all my friends who helped me I am very blessed to have good friends.
