But far less risky than tailgating trucks at a few feet or inches.
Those familiar with "Solo 2" autocross (timed runs through pylons), will
recognize that increasing street car tire inflation pressure is one of
the very first things (after cleaning out the trunk) done to improve
handling in order to reduce times.

They also recognize that such changes are for the track, and they change
the inflation pressure back before driving home and around town.

Most reduce inflation pressure because of ride quality issues, not any
desire for loss of handling.
Some just refill their trunk!

It actually took me a minute or two to figure out the units - and even
then I'm not quite sure.
The kN/m^2 are bar. 1 bar000 Pa = more or less atmospheric pressure
Keep in mind though, that when referring to bars, one usually refers to
relative pressure. If my tire has 2 bars, it means it has 2 bars
overpressure vs the atmosphere. Therefore I'm somewhat unsure about the
graph. And I guess that's why scientists love SI units like Pa ;-)
No real relevance - I wouldn't expect Prii to come with anything but
radial tires. I have a 40 year old classic that came with radials back
Keep in mind though that the higher the speed goes, the less important
is tire drag relatively to air resistance. Latest at quick country road
pace (100 km/h, about 60 mph) I wouldn't care so much about tire drag
and more about keeping windows closed and not having any added air
resistance. But then, a riced Prius with spoilers and the like is rather
