I have a couple of inboard videos from a mobile phone, but I haven't figured out how to edit and upload it.
Helmets are required. I have spent some weekends like this, and i have seen some cars flip over. It happens. In an F20, I don't think the helmet makes much of a difference, but in the older cars it definitely helps.
I haven't seen any successful attempts to fix the drive mode in DSC Off yet. It's the same with the F30 range.
