ive been around racing school's, driving event instructors etc.. alot and trail braking into a corner like turn 2 at laguna is not something they would definitely not teach early on its a hard corner to do it properly on because you need to trail so deep into it for it to really be significantly effective. im guessing 90% of the people would not be up to speed enough for it to even make sense. and even if they were, theres a good chance they would not be ready for that technique.
i have definitely heard instructors tell their studends to do their braking in a straight line, ive heard this alot actually when they are teaching real beginners. and i agree with it, its not something you need to do until you have your driving and car control down very well.
and as for all the formula 1 stuff, yeah i agree with you on most of what you said. that video was literally the first one i could find that had the brake and gas meter thing. and vettel is definitely an amazing driver, anyone in formula 1 is extremely good, even if they did just bring in lots of money to be able to race.
but yeah, im not a very big fan of formula 1 right now. thats why i wish racing got more coverage in the U.S. because half the ameture/low end professional racing is amazing racing to watch. and much better than formula 1.
i like watching grand am/continental tire, ALMS, indy, mx5 cup, etc... more than i like watching formula 1.
