Let's show vintage racing pictures. I'll start.

Is the Chevron a right hand drive car? It looks like he is on the near side of the car.

If he is on the right side, maybe he has a limited view of Morton coming up on him and maybe he is giving himself more room from the stricken car because he doesn't have as clear a view from the other side of the car.

Most Chevron cars are RHD. They are an English company.

The Chevron is RHD.  Chevron is an English race car manufacturer with all sorts of credentials.  The B8 was a 2-liter sports car championship car from the mid-late 60s.  They came with BMW or Ford Cosworth 2-liters.  Tube frame and aluminum panel chassis.

The two cars leading the yellow car had cars to their right. They both left room for these cars and seemed to have "situational awareness" into and out of the corner.  The yellow car was, at first, following them then suddenly switched lanes going into the corner....

This concept of "lanes" on a race track is a new one on me.

The concept of requiring "situational awareness" doesn't apply to Morton, apparently.

Brian has severe hearing loss, if that could be a factor.

He also doesn't seem to have eyes in the back of his head. Might have been useful in this particular corner.

I think Morton's view out of his front screen might be more relevant.  

I don't know about you, but I think if I was driving the Chevron my attention at that point might have been on the cause of the smoke/steam ahead, the stricken car on the left and the cars that were taking avoiding action by moving right. 'Mustang on Grass' is a dish I think many of us would tend to give a wide berth if at all possible.

Following an incident when a 240Z tried to use a B8 as a launch pad, Chevron have MODified one for Brian Johnson's next race:

In line

In Line

Off Line

 

 

The Yellow car changed lines. It started following the  Daytona and the white car but then changed lines to  behind the Mustang.... all under braking.

Cold brakes or no brake pedal applied could have also factored but not keeping the line under braking seems to be the first error.

Yesterday you were talking about "lanes" (?!) and now you're talking about "lines".

The yellow Chevron moved from the left side of the track to the right side of the track - clearly to avoid an incident unfolding on the left - but he was also taking The Racing Line.

You've mentioned "under braking". Why was everyone braking there? Turn two is not a normal braking point, it is little more than a kink between turns 1 and 3. The reason they were braking there was - as I have pointed out - the incident still unfolding on their left with a dramatically slowing car emitting steam/smoke.

 

Key point in all this is - of course - that the Chevron was well ahead of the Z at all times. Morton simply drove into a reducing gap and hit the Chevron on its rear quarter.

That's a lot of energy over a typo.

The teams have radios and accident locations are nearly always are broadcast immediately.

The two cars in front held their line, most likely because they knew or anticipated 2 abreast going into that area (gathered from the 2 abreast since the start of the race).... and/or they checked their mirrors.  The yellow car changed lines going in to a turn braking.... that is not best practice. Especially when seated on the right w/o a blind spot.

Not for the first time are the two of us looking at the same thing but seeing differently. You're pointing at the yellow Chevron and accusing it of "changing lines going into a turn braking", but that's exactly what Morton did to the two 911s after the green flag. He simply outbrakes them going into turn one.

So you're pinning the blame 100% on Johnson in the yellow Chevron? Amazing.

Here's another pair of freeze frames. The first one shows cars ahead on the grass, and they are on the grass because they are taking avoiding action. Three abreast isn't going to work. 

The second shows the stricken green car on the left side of the track with the Cobra Daytona passing it. Morton has driven into the Chevron between the first car half-spinning off to the left infield and this stricken, slowing car ahead. If you want to talk about "best practice" I suggest attempting a pass into a rapidly reducing gap - with two cars ahead on the grass and a dangerously slowing car on the inside - might not be 'best practice', to put it mildly.

100% Morton's fault.

 

[240260280]

I'm not blaming anyone. Perhaps as you suggested above, Morton may not have braked sufficiently  or he had cold brakes... however, going into that area, Morton's line followed the Mustang and the yellow car followed the Daytona.  In your last picture above, the yellow car is not behind the Daytona but between Morton and the Mustang. It changed lines...but the Daytona and white car did not.

A comment was made about radios; no, they don't have radios necessarily.  This is vintage racing, not pro racing.  And John's brakes were not cold.  He just came out of turn one.  John drove into the back of Brian, plain and simple.
