Sorry for the late reply, here's how you escape. Take a relatively fast car and as you're coming down the hill after the tunnel just stick as close as possible to the right of the track and crash into the corner next to the tyre barrier and voila!!! It's easier to get out than the one in GT3 in my opinion too. Here's a photo I took that I almost submitted for the photomode comp this week of me and my skyline outside the track
As for some settings, start with the LSD, change it to something like (5,60,5) you'll get better turn in. Set the toe to (2,6), turn of ASM and turn down TCS to like 3 and that outght to give you a good start. Thanks to roadrunner for those settings, he is an F1 guru!
Have fun y'all 👍
