TBH thought, it's up to the lapper to lap the lappee, so try slowing down a bit and taking your time to pass. Anyone behind you will either do the same or crash. The Super Aguris are 5-10s off the pace of the rest of the F1 field and I don't see Schumacher or Alonso crashing into them. That's because they approach them with care, make sure they know they're behind, wait for a safe moment and then overtake.
A major part of being a good racing driver is having brains. Being fast is all very well, but if you can't pass through traffic or overtake someone well, then you aint gonna get very far. Some of the best drivers I know are on the pace but not the fastest. The guys who win are those who are awesome through traffic, considerate of backmarkers and have their head screwed on. If you go and race real cars or karts with the attitude that everyone slower than you should jump out of the way so as not to spoil your hotlap then I guarantee you won't win any time soon.
IMO, they were wrong to ban you if you were indeed just going slowly, and I don't agree with anyone that says you should race if you're too slow.
