I mean, if it has zero safety concerns and it's possible to actually go 1000 MPH on the freeway, then sign me up! Who wouldn't want to get there faster if there were no downsides?
Even in gaming, less demanding games can hit 1000 Hz and console emulators will benefit from reduced latency too; you could actually beat CRT latency.
OTOH, it's freaking hard to figure out safety at even 100km/h.
