Sorry, you have to work that out on conditions, there is no magic answer
It depends on so many things, you can only get there by trying , failing , and work it out
Bottom line, and we should close this out, you need to be set up before the strike, if you are attempting to capture it as it hits, you have already lost. Do need night shots on passing traffic etc , to get a feel, using tail lights of the vehicles. Experiment. The variables are large, and the variation of equipment as well, just go try the test shots. I used to do this on film which was expensive, you can get an immediate view of what you are doing now.
Please no more on this, way off topic
