Why cant the speedo keep up?

The sample rate of the sensor may be lower than rate of change that the vehicle is experiencing. Probably not but I certainly don't know for sure.
Either way, if it was really counting by 1 as you went WOT in 1st gear it would be changing so fast there's no way you'd be able to read it anyways. It would certainly be useless.
So you wrote the software? I'd be willing to be it just updates the current value based on control inputs of throttle/gear/steering rather than observe the rate of change between the rendered vehicle and the road underneath it.

I konw that the video games use a sensor on the car that shoots downward and mesasures how fast the ground is moving under the car. Opposed to the s2000 which uses rotational tire movement to calculate the speed.

The speedo is more accurate because it skips numbers. The operation of a real LCD light is slower than what a computer would simulate in a video game. It will take too long for a real LCD to display every single input in such a short period of time. By the time the LCD finished diplaying 45...46...47...48...49...50 mph you'll already be doing 60. Maybe if you put our speedo in a slower car, the acceleration will be slow enough for the LCD display to keep up with.
The reason it appears to keep up in video games is because you aren't looking at a real LCD display, you're looking at a computer simulation of an LCD, so it can refresh it's display at a much faster rate.

When your accellerating that fast the RPMs are whats important IMO

^ ditto
on a side note...has anyone ever notice that our speedo will not show 1 mph?

I've heard that before but I swear my speedometer does show 1MPH. Unfortunately, the weather probably won't be nice enough to check for another couple of months.
