I have another idea for spicing up the season:
A pre- and postrace interview with the teams.
It would be the most fun, if each team/driver wrote some preview quotes on each race, summed up on a single page, much like F1 does on their site: https://www.formula1.com/en/latest/headlines/2017/7/hungary-preview-quotes.html
In the same way, we could have postrace quotes setup as well, instead of only a handful using the race thread to comment.
Just like I think it's a good idea to give extra points to fastest lap and participating on the server at all, dropping comments on the upcoming race could earn each team a point or 2. Likely some drivers don't even bother racing 10 laps or go for the fastest lap, so maybe they'd like to earn a few points on commenting.
It could be set up much like the Protest report form, with some basic questions to answer, which each driver then send in.
Example of generic questions in the pre-race quote form:
Q: Do you enjoy the upcoming track, pros/cons?
Q: What's you thoughts of rival strenghts/weaknesses here?
Q: Status of the team so far and goals for the race?
What do you think, waste of time or maybe engaging for PRL community?
