I think this is very bad for F1, too much danger not for lifes but for the sport in general.
F1 has a lot of history. A lot of drivers and legends among them raced for victories and titles for glory. They all had the balls to push and the talent to do that on highest level. Danger was all around yeah, so they were mature people, mature drivers, 30 years perhaps when started racing? Talking about times of Fangio. Its very normal that as years pass by that, those boundaries will be lower and lower, in terms of youngest drivers. We saw many in the last 3 years to drive with only 19 years. By then, when i had 19, i was only able to drive my 75hp Corsa while someone else is controling a monster, and what else is more important, destroys the picture of F1. F1 isnt considered as the BEST 24 drivers on the planet? Of course there are legends out of F1, like Loeb who is i assume better than half of the legends list in F1, but my point is, if people with only 17y are entering in F1 and racing in near future, lets say on 18 years. How can be they titles as "one of the best drivers in the world"
Its bad for F1, i hope you got my point.
ps. i forgot to include money issue ... sponsors etc
