I'm sure this has been discussed before many a time, but did anyone watch Clarkson driving round the ring on Sunday on the 'best of Top Gear' programme? 
  Am I right in thinking cars and bikes taking what appeared to be quite different racing lines would be an extremely dangerous place to be on a bike?   
 It seemed huge, overcrowded with cars, and not an appealing prospect in the slightest.   
 I know people who have done it love it.  Am I just being cowardly?
