In my opinion it is a foolish driver who puts 'greasing it on' ahead of precision. Sure you should aim for the spot AND try to minimise the thud - in that order.
Wizofoz is quite correct, a positive touchdown minimises tendancy to aquaplane on a wet runway, further to that (I was told by an old pilot many years ago) drawing out the touchdown or greasing it on increases tyre ware (delamination) - not sure to what extent this is true these days (better tyres) but it makes sense, the sooner the wheels are doing the same speed as the aircraft, the less rubber you leave on the tarmac - anyone else care to comment on the validity of this. Points about spoiler deployment etc are also valid.
By the way, I'm not talking spine compressing 'arrivals', just a gentle, but positive touchdown - ask Boeing or Airbus how their aircraft were designed to be landed!
