I was probably only a few minutes behind this, we approached as traffic briefly slowed, saw a fire ahead, it quickly got quite intense as we passed saw it was in the field I thought little of it but my work mate in the car saw two people running into the field so assumed something had happened. I just saw a van and car on hard shoulder, no obvious signs of any crash
It wasn’t raining at the time although it had been quite heavy about 30 minutes previously so road was wet but I wouldn’t describe it as hazardous driving conditions, traffic on the motorway was light, perfectly straight bit of road
No idea how he could end up where he did given the conditions, but I don’t recall a black Ferrari passing us in the moments before so suspect excess speed wasn’t a contributing factor, although that’s not to say he wasn’t pulling some dickish type of move at the time or someone didn’t pull out in front and he over reacted on the brakes and lost it, basically could be anything and possibly only the driver knows why
