Welcome, Maura.
I live even furter away so I can't help you with tutors in your area, but I do have some ideas which may help.
1) If possible, encourage her to wait a while longer, until she builds up her exective functioning skills. In Australia, we don't learn to drive until we're 16 years old (minimum). difficult child 1 knew he would be a danger on the roads and so chose to wait a few more years, he didn't get his Learners Permit until he was 23 years old. He got his licence a year later at 24, bought a car which he drove for a year until he wrote it off in wet weather and was unfortunately uninsured (he hadn't realised). He had been driving for a year before he had the accident, which is a sign that he definitely had improved due to the delay.
2) What made difficult child 1 more able to learn to drive, was honing his skills and reflexes in computer games. We were also able to get our mitts on computer games which are designed to rehearse driving skills directly, as well as road rules etc. A great DVD ROM that was brought out by NRMA, one of our Aussie road service companies plus inruance company, teachers young drivers how to assess various driving scenarios (including aftermath of accidents). it very definitely teaches executive function, drills it well.
3) difficult child 3 has recently been given a "prescription" for computer games that build exectuvie function. Wii Big Brain Academy and Nintendo DS Brain Training are good ones for any age (I play them too, both to keep my own brain functioning, and also to 'compete' with difficult child 3 and give him someone to try to beat). We were also told to play Zoombini games where we can find them. That sort of thing.
Watching my kids play computer games, I watch their fingers fly and imagine their brains coordinating all the steps, the click here, a flick there. Driving can be like that - when we're first learning, we panic at the thought of driving in a straight line, having to slow for a corner, flip on the indicator, use the brake properly and (heaven forbid if we're driving a manual) having to slip the clutch, change gear, manage hill starts etc. But a kid who is skilled and well-practised in a computer game, is a lot like an experienced, confident driver.
For a kid with learning problems, learning to drive can be done but it takes much more practice, much more drill and slow, careful steps. You COULD pay a fortune for a personal coach with special expertise in NonVerbal Learning Disorder (NVLD), or you could (while you wait to find the right tutor) try to find lateral-thinking approaches that will eventually help your daughter boost her overall skills and hopefully help her work closer to her (and your) goals in this area.
Despite his car accident, my son is back behind the wheel (of his wife's car) and does all the driving when they're together. She doesn't have NonVerbal Learning Disorder (NVLD) in any form but still feels safe when he drives. That's a good endorsement.
When it's difficult child 3's turn, I have fewer concerns. he CAN multi-task (unlike difficult child 1) and has had the road rules memorised for the last nine years (since easy child first brought home her Learner's Permit and the accompanying book of road rules). In a year's time he will be eligible for his own Learner's Permit. I will probably make him wait another year or more because he DOES get flustered and stressed, but then again... I might allow him to give it a go right away.
It really does depend on the child himself, and how well he is able to function, as well as how much help we can give him to learn the skills sufficiently, to be as safe as possible for others as well as himself.

, but I've lived with a NonVerbal Learning Disorder (NVLD) all my life. Except for the social skills part (and I never was that great at reading faces either), I can tell you that it can be impairing. For me, it is severe--IQ is 120 verbal and 85 performance so I sound very bright, but can't learn to perform simple tasks without extreme help and repetition. And I recommend that your daughter do what I did--REPETITION. She may need three driving courses and extra time with you and dad in the car before she can get the hang of driving. It took me forever to learn to drive safely. Once I did learn, I really did well--I had one accident at 18 (I still hadn't gotten the hang of it and tended to space out on the road), but no accidents since then. There ARE a lot of dings on all my cars--she may not have a good sense of perception (where she's at) and may hit things. I have a spatial oreintation problem too and dings on the cars are just part of who I am.
