So which programme should a young driver prefer? Let's take a look at Gravity - d'Ambrosio got one year, but seems to be out of the game now. Oh, and many drivers could have done more in their racing career, not just the Toro Rosso ones. You could turn it around by saying that without Red Bull's support and with the help of an alternative sponsor/driver scheme it is very unlikely either Alguersuari or Buemi would have had 3 years of F1 by now, perhaps no F1 at all! Red Bull programme is hard, because there have been many drivers and the competition is tight. But it also gives more opportunities, because Red Bull has a special junior F1 team, where you can actually race. No other junior programme has such luxury of additional two F1 race seats just for you, which means that graduating to F1 would be more difficult via alternative junior programme.
