Something occurred to me recently: assault is defined as action which causes fear of harm, and a car tailgating a bike could easily be construed as threatening. Much more thorough explanation of assault. Here's my reasoning: 1. In a collision, motorcyclists have a high chance of being injured (in comparison to someone in a car, at the very least). 2. The above is obvious; a person could reasonably be expected to be aware of it. 3. A reasonable person would expect a motorcyclist to feel threatened by a car or other larger vehicle tailgating them. 4. The driver has perceptible means to enact violence immediately. 5. Tailgating is illegal, anyway, so I strongly doubt there is anything which could be used to excuse it. EDIT: 6. If the motorcyclist is travelling at the speed limit, their ability to legally escape the situation is very limited. So, I'm wondering if tailgating a motorcyclist would, indeed, be grounds for prosecution. Even if it isn't strong enough to be taken to court, if there's enough there for cops to charge the idiot (but drop it later), that'd still be cool . Could any of our lawyery types provide some input? Its not particularly relevant to me right now (don't have anyone I could try it on 8-[), but its an interesting idea, and I figured it'd be worth bring up. P.S. I did a search on 'assault', checked at any threads which looked like they might be related, but found nothing.
