A movable front wing is a recipe for an unintentional oversteer event isn't it? The teams already know how to slow cars down as they do it a couple of times every race - add weight. In my opinion F1 needs to bring in a handicapping system based on WDC points. The system would be cheap and safe and predictable and encourage continual performance improvements throughout the season. I realise that it is viewed as "penalising success" but if it means that the racing is less reliant on random factors such as safety cars then it can only be a good thing. I would start at 2kg per WDC point and tweak the system from there.
