Do you know how many laps of the race was completed by the time Senna crashed??? I am certain you have don't know that.
Senna asked after qualifying to change the Steering column, as he was uncomfortable with the original one, Williams engineers don't have a complete set of steering column for replacement so they have done a cut and weld job which needs about 36 hours to completely settled but with only in less then 24 hours the car have to compete so the risk of anything goes wrong was present.
In reality, his steering column broke when he tries to overcome the slightest mistake on the last lap. At the start of the race their was huge crash which brings the safety car and the safety car remains on track for 5 laps. On Lap 6, the race restart and Senna was in front but as soon as he enters Tumburello there were sparks from the rear of the car, which means the car is bottoming out on the corner.
So next time Senna tries to avoid the kink present on the track on that corner by taking it in between his car's nose and left front tyre but somehow the left tyre hit the kink and the car goes towards the wall to avoid a direct contact Senna tries to counter the steering in opposite direction causing the newly weld column to broke, leaving Senna a sitting duck. Even then it is not the crash that kills him, had it not been a small piece of suspension ricoheting back and piercing his skull, he could have suffer some minor injuries but nothing serious at all and could have come out of the car on his own.
As for Kimi reminding you as Senna, I disagree Kimi is not Senna never was and never will be, the kind of determination that Senna shows Kimi lacks that determination.
