Since the last post this game got quite popular by the 2007 when I joined. Since 2009 is slowly winded down and finally after 10 whole years of playing I finally left in 2017. Not because I was getting tired of it, on the contrary in fact, but because all my long time buddies left some time ago and the new younglings just didn't have the same pedigree.
To me it's still the most accurate car physics game there is. At least one commercially available. You owe it to yourself to give it a try

Just a heads up - it's 99% multiplayer oriented with around 1000 people playing at its highest peak when I left 4 months ago. Driving offline solo or vs. AI is possible however.
You can download the demo and play single/multy without time restrictions but of course most content is locked. It's not a big download, you can drive with KB/mouse/Wheel or gamepad, it isn't resource demanding (main dev is very considerate of that). There are 3 cars to choose from and one track with two configurations.

The person with the longest distance is not very far from 2M km I believe
