not necessarily the cars will understeer.
and im not sure if DC does like understeer.
but i know what u mean with the drastically reduced aero grip, altho the slick tyres would bring enormous mechanical grip thus restoring the balance somewhat
it would be fascinating also, as a driver would have to take more care looking after his tyres. - as there is more mechanical grip.
i think TC should be banned immediately.
and also i think tyre warmers should be banned.
some of u may think that would be dangerous, but it would not be as the FIA could increase the ground clearance so that any F1 car on cold tyres with lower presures would not ground out.
also i think the irl or cart do not use tyre blankets and they are fine. this is where JPM or other drivers could really use their skill driving on cold tyres
it would make the start of the races, and pitstops with fresh cold tyres really really interesting
