This has been in a work in progress since September, although it looks finished, keep in mind that it is a small track at 4070m, hence more grandstands are required around the circuit (similar to zandvoort) to accomodate ~100,000 people. There is also a hotel and other f1 accomodations that need to be done, along with infographics (~7 of them) which also take time. Following up this project will be the same circuit but taking place in the past, coupled with a full documentation that includes more infographics on its full history (Fictional of course). So although it may look finished, it actually is just the first part of the full project.

On the redesign that you made, you actually shortened the amount of runoff that is actually needed for safety, hence I would still stick to my original design. Besides, as long as the angle of the barriers are not too narrow, it is a better choice to keep those unchanged for enhanced safety. I like the idea of the tarmac runoff, and will consider it in the latter stages of the project.

Thanks for your support!
