The BF1 isn't the most popular car online at the moment. As an F1 enthusiast, I can't help but feel that the current driving experience is about 2 years out of date. Recent regulations have abolished traction control (which would make a big difference) and rpm is limited to 19,000. Turning the TC off at the moment makes it practically undriveable (and I don't think it's just down to setup), F1 drivers have said the new non-TC cars are quite easy to get used to, but this isn't the case in LFS.
I think that the current BF1 car settings could just be altered (maybe a new car model if eventually) so that drivers can have a relatively realistic F1 experience online.
