Well, this is China, and you could end up in a ditch through an accident, but I doubt these drivers are any worse than the average Chinese driver, and probably a lot better/safer. You could also end up in a ditch through criminal kidnapping and evil intent, but this is China...so I think zero chance of that. If the people you are accompanying are those you need to impress (as in, no logistical slip ups), one thing you could do is set something up with a service, but insist that the day or so BEFORE the trip, meet the driver/car for 5 minutes so you can bless with final approval, leaving time to still arrange substitute if you don't like. If just travelling with friends, maybe don't bother with a previous meet-up. That's what I would do.
