I recently turned 18, so my parents signed me up for driving school. When I showed up at the academy, I was surprised by the cars they had available for students to learn on. They told me to pick whichever I liked best, and I chose the Mercedes-Benz G500.
I guess it depends on the country, we have to provide our own cars in the US. I used my brothers small Toyota Corolla so i could do the 3 point turns and stuff easier in a smaller car. If you go too far up the curb or into the grass, you fail. Then after i got my license, i bought a HUGE cheap chevy impala. That thing was a boat, but drove so well.
