I believe Max has replicated the braking/throttle technique of MS, probably passed onto him by former team mate Jos.
I saw an interview with Vettel,he said he once asked Schumi for any tip on how to best drive the first sector at Suzuka ,Schumi just said he didn't have any special plan/technique for that ,he just did it... Max does have his own style of course, which is still a bit controversial to many,when he was asked how he would handle the overtaking with the new cars this year he just said he would just have to make the passes at a higher speed
MS had a unique technique, and Jos would have had access to the overlay traces. Probably wrapped them up in a giftbox for Max's 6th birthday
Schuey's technique was pretty much an evolution of Senna's technique - One of using the throttle and the brake pedal at the same time to rotate the car mid corner, by multiple short, sharp stabs of the throttle pedal mid corner to guide the car round. To say it was unique is pushing the boundary a little bit!
Senna was stabbing at the throttle from the turbo days to reduce turbo lag. I don't know now you can really visually look at drivers today, and tell any style.. you need to do comparison videos on each corner... the speeds are so high and the cars so similar. While I think its interesting to talk about the driving style - its like karting... you are just on it all the time.
