The s. 172 requirement asks you to state who was driving your vehicle at the specified time, date and location.
Was anyone driving your vehicle at that location at that time and date?
If not, then your vehicle was not involved in the offence alleged in the notice, you are not the person keeping the vehicle that was (we suspect that there is no such vehicle, but that would tend to complicate things), and therefore as "any other person" you are required to provide any information that is in your power to give and that might lead to the identification of the driver [of the vehicle involved in the alleged offence at the time, date and location specified in the notice]. That information would be that your vehicle was not at the location specified at the time and date specified as it was <wherever it actually was> at the time.
As has been mentioned, there is a fair chance that the police will drop the whole session out of embarrassment.
However, if they were to reissue a corrected NIP, and more relevantly the associated s. 172 requirement, as a matter of law the original defect would not invalidate the NIP (for the purposes of s. 1 RTOA 1988) as you have not been misled by the error. Whether you would be able to put the prosecution to proof on the point by raising an issue at the half way point of the trial seems uncertain.
