He has never been a 'boring' driver so not sure how you've come to that conclusion tbh. Always pushed his car to its limits (often to his detriment granted) and did some phenomenal overtakings. Recently held the record for most fastest laps, iirc. Started off great in his McLaren days and drove some fantastic races. That last lap overtake on R134 at Suzuka, one the
outside against Fisichella was one of the greatest F1 moments I've seen since the early 90s.
Vettel on the other hand has had a superior car and simply let his onboard computers do the rest having all the reliability in the world - something Kimi never really had. He's never been under pressure over the last 2season. Raikkonen was always the underdog catching up in a bricker car against Ferrari or Renault. And still did so admirably in most occasions. Went to Ferrari, achieved his goal and then regressed, imv. Suggests he was only after that 1 championship title which is a great waste of talent, imv
Doesn't say much in front of the camera but has some great one-liners over the years. I think you might be confusing his perceived boring character on TV with his driving. He also appears to be a bit of an alchie.
