Someone said "Aston Oval" yesterday at RTFR XL. Although it's not quite an oval, I revived and adapted my little bowl script and figured out my idea would work a little like 60's Monza. That's why I added a few hay bales here and there...

- pretty quick track
 - works well with LX6 (the most vintage car in LFS, needs slightly more ride height) or FZ5
 - even works with BF1 :-D
 
- smoothen the typical entry/exit lines with appropriate concrete ramps
 - build some concrete buildings close to the track (to get some 60's Spa feeling)
 

 sure, go ahead, I'm curious what you will do to T1 xD
