key word reasonable. IE you have to make your point to a jury. If a violent driving person, that then threatens me with violence (although within his car) is plenty of reason to believe its a credible threat. And retaliating with OC spray to prevent further harm to both parties would be acceptable. At least that would be my case.
Have to remember every time you see the word "reasonable" in law code, you are immediately in a huge gray area.
And yes a defense for battery is assault by the other party.
