Fair enough. It's that flexibility that it offers that can make it worthwhile. I just found my times of driving had too much competition (Fri and sat nights) and the wear and tear, tax, insurance, and the time invested didn't make it worthwhile anymore.
I got onto it pretty early and it was actually white profitable back then...
Those were the days..
Yeah I don't think I could carve out a full time living doing it, but knowing if I have an errand to run, or there is an event on nearby I can just switch on the app and see if I can pick up a fare or two.
