I think the problem with Jenson is not necessarily his consistently, it's that he has to feel completely confident with the balance of the car and if it's a bit twitchy then he drives accordingly which results in less heat to the tyres.
Lewis on the other hand does not care at all, will grab it by the scruff of the neck, drifts it round corners and is very exciting to watch.
Did anyone else notice in Monaco, after the red flag Jenson was on prime, both Vettel and Alonso were on options yet he kept up with them, impressive.
