I can see why people are saying Kubica was stupid to go rallying, but hindsight is always 20/20 isn't it?

That was a complete freak accident, pure bad luck - proved by the fact his co-driver walked off unscathed! The argument to ban drivers from other competition ironically would hold much more weight back in olden days when it was rife, as the cars are far, far,
far safer now... but that is a moot point really. You don't see these kind of clauses applied in regular jobs, and after all it's just a job to the drivers at the end of the day, i think they should be allowed to have a free life outside F1.
Don't know about equal car, but as I've already highlighted, they certainly didn't have equal personnel on the engineering side of things. Senna had an inexperienced race engineer, which for a rookie driver can prove (it has in the past) to be a disaster. The other side of the garage had a race enineer with a decade of experience in F1 at lower level teams - i.e. was used to exactly the environment that would have been at HRT. I've said before, as far as I can estimate, Senna may have been making up half a second to a second per lap against his various team-mates just to get an equal time as them in a better set-up car. Overdriving the car as a result and thus spinning / going off track more frequently than his team-mates because he was under pressure to beat them. Honestly - look back over the whole season and you'll see that everything I'm saying matches up with the pattern of his season...
I honestly think that not just a lot, but the majority of F1 fans simply don't understand the importance of the engineers in setting up a car to its optimum level. It drives me absolutely nuts!! 
Thanks for saving me a bunch of typing with that post, i completely concur.

Blind leading the blind for him last season.
edit - NEWS: I just read that Heidfeld will test for Renault in Jerez...
