Agreed about a lot of SUV drivers. We do have an Explorer, the 19 year old didn’t learn to drive in that vehicle (that was our Taurus and the Tauri that the drivers’ schools seem to favor), but he was anxious to use it.
I wouldn’t let any of my kids drive my SUV’s until they had been driving my wifes car for at least 4 months. They needed to get their skills first…Then I took them out driving with it so they could feel the difference. I wouldn’t allow them to drive it on their own until I felt they were ready. For my oldest that was when she was in her second year of college.
