I didn't have any major issues with Uber/Lyft when in LA last year (one minor one but fixed within minutes once I contacted them), but was taking it at off-peak times. It's a really easy and fairly affordable way of getting around.

Otherwise if you want a fixed rate I think you could look into shuttles or private transfer services. I was looking mainly at airport transfers but I think Supershuttle/Execucar might do point to point transfers for fixed rates booked in advance.
