I live like two miles from ACH and this is amazing, really accurate work. Was impressed to see you're in the UK! If there is anyway I can help, like if you need additional resources let me know! Also donated for the extended VIP version, email is renehourian@gmail.com . Cheers.
We have some other really cool roads near by too like Little Tujunga Canyon. Really tight and technical almost tarmac rally stage like strip of road. Spunky canyon above it is also really amazing too, similar but less abrasive surface and more flowly on camber corners. Malibu canyons also super fun. If you ever have the urge to recreate those let me know.
