I'm a fan of brake lights really. Half the skill of overtaking is outbraking your oponent, and if the guy behind can see your exact braking point then he can easily work out where he should brake, so this should lead to more overtaking, which has to be good.
MS is probably saying "everyone follow my example" and for once I'm in favour of them doing this, and as Hendrik says, it could stop accidents happening.
