I do allow certain people to drive my car because
1) I can't figure out handling issue (over/under steer)
2) I can't figure out why the car is loose (sp)
3) New guys but with strict instructions to drive at half throttle and to obey my commands
4) the new guy is one of my kids
BTW, what were you thinking allowing a person never driven 1/5 before driving your FG. I wouldn't. You're a brave soul....can I drive???
