I have seen that as well. In the corner before the crash, they were less than a car length apart, that's my guess. That stretched up a bit, right in front of the critical corner Rosberg lifts slightly, NK goes through it, distance 1.5 car lengths which means about 7 meters. Speed in that corner, 220? Let's say 200 to be safe. That means about 55 m a second, which translates into crossing that distance in 0.15 seconds. Despite Karthikeyan not standing still but braking, we can add an extra tenth or two to close up the gap. But still he was on the racing line. Nico never had a chance there really.
Your estimations are about correct to me. The 7 meters and the 200kph(race pace with heavy fuel as this was at the begining of the race) and everything seems perfect untill the bold part.
This is a HRT slowing down(was NK fulling braking, ie, braking as much as the car could as in a qualifying lap??? I doubt, imo he was rather "slowing down" rather than braking as it would be totally non-sensical to do brake 100% there) and it wasn't by much, as far as the eye can spot, and even if he was fulling braking, HRT have very low downforce, he was on quite used tires, with a lot of fuel onboard and "only" at 200kph. The G-force in braking grows with square of speed due to downforce growing like that.
With all this accounted, I highly doubt NK was diminishing at more than 1,5/2 Gs which would decelerate the car way less than most people are assuming on this case.
But instead of making guessings and etc, I counted the time it took in the "real time replay"
From this frame(1) onwards, NK starts to slow down as both keeps getting closer to each other as can be seen on frame(2):
From frame(1) untill frame(4), the frame just before the collision, it took around 0,85s
Or even pushing in favour of Rosberg, if you wanna choose another place to start the countdown, from frame(3) to frame(4), it took around 0,5s
Even "pushing" in favour of Nico, it took way more than your guess and that's because of the "braking thing" I pointed out earlier
At the very least, Nico had half second to deviate. It would just need a slight steering movement to either go to the tarmac run off or to the inside.
Kimi had even less time to avoid Lewis(after his puncture) in Germany and still reacted quicky enough
You have seen it in slow motion replay, that's why you think Nico had time to avoid that crash.
Don't remember the accident was shown in real time.
It was shown both in slow-mo, obviously, and in real time
