A lot of NASCAR fans argue that F1 is just that - driving skill has been replaced by technology. I think that's nonsense. Better cars are an advantage, but ultimately, it's the driver's nerve and imagination that wins. I'd choose a lesser car with a greater driver any day.
Completely agree. On Top Gear they have a segment where they have a celebrity drive a 'reasonably priced car'. They had to create a separate scoreboard for F1 drivers, because they are all so much faster than anybody else.
I wouldn't. Not in F1, at least. Not if you wanted to regularly come in the points. You could stick Vettel in a Marussia, and he'd still finish near the back of the pack.
Vettel won his first race with Toro Rosso. While he may not be able to win in dry conditions in a Marussia he could certainly get the most out of the car, and help the team build it over time.
