Safety of LAX shuttles?

[Drew]

My wife will be traveling alone and arriving at LAX in the evening. She needs to get to a hotel in Burbank, so I reserved a car (GoSedan) to take her there. I think that she will be the only passenger. However, she thinks that a shared van would feel safer, as there would probably be other passengers in the van, as opposed to the car. I've taken a shared van from LAX before and found that it took a long time to leave the airport, because the driver kept circling and waiting, hoping to pick up more passengers, before finally getting underway. The cost for the sedan is more, but not significantly so. I want her to have a comfortable ride and get to her hotel in a reasonable amount of time.

Any opinions about the safety of those drivers? We live out of the country and feel a bit out of touch with these kinds of things. Thanks.
