cvt gearboxes are banned from most racing series, the only time they were use in f1 was back arround 1993ish by williams (it was whichever coulthard first started) this was banned later in the year. as for most racecars they use straight cut gears without syncro-mech which allow clutchless shifting. after a little research i found this was last used in f1 about 2005 now the seamless shift systems use an electronic clutch. as for alonso stomping on the throttle he would have been doing that to try to carfully match the engine revs with the gearbox so the gears will engage. thats why the box would shift up ok but not down.
