And the way some drivers treat the elderly is horrifying! I think you can tell the character of someone by the way they treat other drivers, I really do.
We have a grey Grand Marquis. People behind us either think we're grandpa or a cop. People show their characters by how they react to that car. It's been very eye opening.
Until she gets more experience and shows more confidence, I will continue to be a bad passenger. Yet, she can't get any experience because I won't ride with her. ARGH!!!!!
Are you doing the sudden intake of breath when she scares you? Try to not do that, it's not helpful. If she's doing something scary, try to tell her what she needs to do, in as neutral, calm, QUICK voice as you possibly can.
Also, do you have ANY friends or relatives that you could send out with her? My mom was borderline useless in teaching me to drive, and I had a late birthday so my DE course was after I was old enough to actually have my license, so I spent part of my summer taking paid-for driving courses. After that, I had a dad and stepdad who were better, and if they hadn't been around my mom could have drawn upon several friends, most likely the one who always parallel parked her car on the hill outside their house in San Francisco (she'd honk, double park, throw it into Park with the e-brake on, and he'd come out to park), to go out with me. For me, males helped much more than females. Do you have ANY friends, or spouses of friends that would help?
It's interesting what you said about her driving test. My brother learned to drive in Miami, and he is one of the best drivers I know. Always on alert, extremely defensive (and a bit offensive, LOL, but that's calming down the longer he's out of FL), and that's how he learned in Miami, though I dont' know if it was learned in his driving course. My brother later taught me to drive a stickshift, after my mom, stepdad, and dad all failed miserably in teaching me. The right teacher, even if they are your baby brother, is amazing!
Around here the driving school with the best rep throws kids right into one of the most difficult driving situations locally (entering a busy interstate from the left-hand side) and then works their way down... I guess they figure once that's out of the way it's all gravy. Personally, I think spending more time on the road teaching kids the right way to handle situations would greatly decrease teen accidents - how else are they going to learn?!
Then don't go to that school!
My husband got his permit but hadn't had the driving courses. His dad needed to drive a vehicle across country, from WA to NJ, one summer. Hubby drove quite a bit of the way, on the highway, and thinks fondly of the nice flat roads through North Dakota and other middle-states. That exreme experience helped him, and when he got back to school and had his driving course, he was by far the most experienced and best driver in the car (the teacher wouldn't let anyone else drive on the highway!).
