I always wondered about this. Who races their cars around like a madman on public roads? Very few I would imagine (and hope), and even fewer take their car to a track. For a Ferrari, possibly a bit more (still probably 99% of the time they are on public roads). But every car review discusses these things at length, as if normal people race around the countryside or mountain roads, putting the cornering and stiffness of their Toyotas and Fords to the test.
Driving a well handling car is noticeable at any speed, any time you are going around a curve, and sometimes even in a straight line.
The first time I drove a 1st gen NSX, I said you could put a dime on the highway in my lane and I could barely pass it with one wheel to the left or right at highway speeds with eases. There is a lot of precision in a good sports car’s handling.
you don't have to drive at 100% to appreciate the driving dynamics. Light and nimble cars feel amazing even at speed limit, e.g 80 km/h on twisty country roads.
