Super car acceleration, normal car braking.
It’s not a great combination in a car that’s heavy, but I guess you don’t sell cars by bragging about braking distances.
Tires moreso than brakes. Ultra low rolling resistance tires help increase range. But they’re crap for high acceleration/deceleration. Not sticky enough (by design) to work in those situations.
Plus they are designed to have low amount of aerodynamic drag. So no aerodynamic grip in fast corners.
On most public roads, if you’re driving fast enough for downforce to be an issue, your poor judgment is the primary factor in any resulting crash.
Truer words have never been said
Which is true but not any different than normal cars. Very very very few cars have enough aero to matter—even on the track.
