спидом
The Russian word "спидом" is not standard. It might be a misspelling or shorthand. If you mean "спид" (SPID), it translates to "AIDS" (Acquired Immunodeficiency Syndrome). Could you clarify?
In this context, 'спидом' is the instrumental case of 'спидометр' (speedometer), indicating the means or tool by which the subject performed an action.
Я посмотрел на спидом и увидел, что скорость превышает допустимую.
I looked at the speedometer and saw that the speed exceeds the allowed limit.
Here, 'спидом' again functions as the instrumental case of 'спидометр', showing the object associated with the verb.
Со спидом нужно обращаться аккуратно, чтобы не повредить механизм.
The speedometer should be handled carefully to avoid damaging the mechanism.
In this sentence, 'спидом' remains in the instrumental case, used to specify the tool or item used as evidence.
