We started years ago by putting our son in the front seat to see what was going on on the road. It's a simple thing but rather than being a passenger in the back playing video games they got to see more. Later as the driving started they got to drive under the learners permit and we would go over the path to/from the few places they would go daily (college.) It's been a year and the planning paid off.
If you want to install a GPS tracker and logger, sure, those are at amazon and more. BEWARE ANYONE THAT POSTS a direct link as it's likely spam.
Also you can install one of those mobile video recorders.
My son recently received his driver license,I'm so worried about his driving, and I can't stay with him all the time, what do you do? does anybody use tracking device to monitor teens' driving? what kind of device do you recommend?
