That's definitely being generous.
Seb felt in control enough immediately after rejoining the track that he stamped on the throttle and spun up his rears while trying to defend.
Which put him almost parked facing across the track in front of oncoming traffic.
The point here, is that Seb blocking the road was not just an act of god he had no control over. It was the result of choices Seb consciously made.
SEB made the mistake and put himself on the grass.
SEB stamped on the accelerator to get back to defending as quickly as possible, at a time where he apparently was a passenger and was "lucky" not to hit the wall.
Spinning his rears and rotating his car till it was facing the wall, across the path of incoming cars.
SEB decided after going off track, coming back on and making a second "mistake" that had him facing the wall, to then crowd an incoming car off the defined boundaries of the race track.
The definition of unsafe re entry onto the race track.
Come back on and make another mistake spinning up your wheels that has you facing the wrong way on track.
Impede another cars progress in an acceleration zone by both crowding them off the track and forcing them to brake to avoid contact with your car that you're still not done swinging all over the place.
Multiple rule violations, sloppy driving and to be quite frank, bullshit excuses, plus stewards with actual telemetry data and every camera angle available = penalty.
It really is that simple.
Seb ruined his own chances, nobody else.
Not a single other person is to blame but Sebastian Vettel.
