If you know the velocity you can find the speed, you don't need a sensor.
Yes. Going under the speed limit is (-) going over the speed limit is (+) going on the speed limit is (0)
Yes, many state highways have a minimum speed limit.
This question makes no sense, what do you mean? the speed of the car does not dictate the posted speed limit.
The fastest vehicle.
No.

No. Missouri has a speed limit just like everywhere else, and going over that limit (i.e. speeding) is illegal.
no, they either have a speed sensor located in the tailshaft of the trasmission or on the newer models it is read from the wheel sensors that are also detect anti-lock brake conditions.
Not for a first offense possibly. Depends upon the other circumstances, too. Say, if the speed limit was 35 and it was snowing heavily, one could receive a ticked for going the posted limit as that would be way too fast for the conditions. Just because there is a posted speed limit, the keyword here is "limit", that is the fastest speed that is allotted for that road ... it is not the 'required' speed to travel.
excessive speeding is going atleast 20 mph over the posted speed limit
Speed sensor needs to be replaced in the engine, look speed sensor up for your vehicle
