you have to watch the black boxes as they record everything, Time, speed, braking etc. can be used against you in a crash.
Also check the insurance, the grandson had insurance when I was taking him out. All well and good until he passed the test, then the insurance didn't cover him and he had to get insurance as a full driver, not on a provisional driver status!!
Crazy, I had to drive him home in his car or he would not have had insurance from returning to the test centre and having the pass certificate!!
Taught him and the granddaughter in their own cars, both had Clios, easy to drive, nippy and had good visibility.
Good luck to him.
