Yeah if a new member wants to run laps with one of the established members in the room with them, then it would be verifiable as long as the fastest lap is put down by the newer member. The online room shows fastest lap for the room and everybody can see it, but If I were to run a faster lap I wouldn't be able to verify the newer members time. Unless they beat my time. Therefore I would just have to sit there and watch, or just go slower around the track.
The problem with handy cam or pic is how do you verify that they are online in a room time trial with all assists off vs practice where the cars work ten times better. Even video they would have to record everything from room entrance to room settings to the best lap and when is all said and done you could have 2 hours of straight video to post as to verify that the fast lap wasn't edited into the video. I think newer members need to be in a room with one of the established members to verify the time.
On the flip side, I can't find the c6 corvette in my lobby's selectable garage. Onyx what c6 did you use.
