It seems each time PD gives us something, they take a little something away. Currently, we're lacking any security measures regarding the validity of any times that will be submitted. However, most of the guys on this forum have known and raced with each other about a billion times in the last few years. I trust 95% of the guys here to run laps as dictated by the rules and the other 5% probably suck enough that we likely don't have to worry about their times meaning much.
I've spoken with Clacksman about running concurrent time trials, but the participation over there hasn't been enough to warrant a second time trial. If there is enough interest, I think multiple time trials are a good idea since what I'm looking for isn't necessarily what other guys are looking for.
If given the opportunity, I would prefer to start with a shitty car on a relatively uneventful track, as I'm interested in improving my mostly lacking skills. Other guys might be interested in the trash talk provided by running something faster on a track with a little more meat to it.
Validating times would be great, but it doesn't even concern me with this group.
