To me it's an extremely clear yes. The only reason I can see why we view this differently is just because we've all agreed this doesn't apply to choices made while driving. But I can't see why that would be the case.
On your second point, the likelihood that speeding will cause actual harm to another person is vastly lower, and certainly not an outcome expected or intended by drivers generally speaking. Seems silly to call that "violence" when we can just call it irresponsible, negligent, etc.
A pedestrian dying because of a driver's decision to speed in this way is predictable, absolutely expected. Shit I doubt my odds with a golf club at a party are anywhere near 50%. So why is one violence and the other not? I think only because we have decided it is not. But again that decision is exactly what I'm challenging. Calling it silly is not a convincing argument to me.
Nevertheless, I appreciate your point. I was thinking only of speeding on highways. Speeding is an issue and shouldn't be minimised.
