This is getting off-topic, but I am curious, why didn't you go with BART in the first place? If you had an hour to call the taxi company and still arrive in time, presumably, you had more than enough time.
I know there are reasons for not going with public transport, but preferring to take a taxi/uber when a train line can get you there in time maybe has more to say about public transport than about taxis. Well functioning rail is typically one of the most effective and reliable way of getting to an airport, and often much cheaper than taxis.
Not OP but many many reasons. If you have the money and you prefer comfort (and/or have kids along) taking a taxi/uber/etc. is much more preferable than dragging several (probably heavy) luggages up and down platforms (elevators may or may not work), walking long paths, etc. especially when you consider the alternative is simply putting luggages in a trunk, sit down and relax, and most likely get there faster. And all of this is before we even talk about any safety issues with BART.
I refuse to take public transit with a checked bag until the NYC subway has 99.9% escalator uptime and escalators at every station, realistically possible with redundant escalators. We will never have nice things as long as we let the trade unions bend us over
