I think Vettel's 2012 season will be most akin to Prost's 1987 season, with Button and Hamilton as Mansell and Piquet, Alonso as Senna!
As Alonso says in the video below, we haven't really seen Vettel winning when he's not in the best car yet, and I don't think Red Bull will have the best car this season. If the cars are closer Vettel will be racing a pack of cars on track rather than mainly himself and the stopwatch and if the drivers around him such as Hamilton, Button or Alonso are on form in comparable or better cars I don't think Vettel (or any of them) will be able to dominate. Plus there may be other teams fighting at the front like Lotus or Mercedes making things difficult.
