What I like about it, though, is that it is a write-in vote, not some pre-determined list. As for Vettel, is that him, or the team? I haven't really followed F1 since they switched from turbo-charged V6s to naturally aspirated V-10s/V-12s (and now they are switching back, from what I hear). Senna dominated, too, but he always worked for great teams. Taking nothing away from either Vettel or Senna, but if the car isn't good, good luck, especially in F1.
I think your comment is far more true in drag racing than road racing. True, parts and teams always have a great deal to do with it, but the ability to be one with the machine is never so crucial as it is in F1 (in my opinion anyway). Wet, dry, different tire compounds, all while dealing with an ever-changing car weight.
