Rule 2
Responsibility
"Rule of good seamanship"
(a) Nothing in these rules shall exonerate any vessel, or the owner, master, crew therof, from the consequences of any neglect to comply with these rules or of the neglect of any precaution which may be required by ordinary practice of seaman, or by the special circumstances of the case.
(b) In construing and complying with these rules due regard shall be had to all dangers of navigation and collision and to any special circumstances, including limitations of the vessels involved which may make a departure from these rules to avoid immediate danger.
Pure and simple, if the situation were reversed, how close do you really want a vessel passing you "at a greater than headway speed"?
50 feet
In the District of Columbia, when two or more Personal Watercrafts are operating at a speed of 10 mph or greater, drivers must maintain a separation of 25 yards.
at least 50 feet
The critical distance a cell must maintain from a capillary in order to survive is rarely greater than 40 to 200 µm. The role that diffusion plays in this process is that it can maintain the concentration gradient required at the cell.
To ensure that the minimum height of their conductors maintain the legally-required clearance above ground. The greater the operating voltage, the greater this clearance must be.

is there a minimum distance between 480 volt phases. ANOTHER ANSWERThere is no such thing as a 'phase-to-phase' voltage. The correct term is 'line-to-line', which is why that voltage is called a 'line voltage'. The distance between these line conductors depends on the value of the line voltage; the greater the line voltage, the greater this distance must be to prevent any flashover. These distances are specified in the utility company's standards or regulations.
100 feet
The distance between two cars while driving should be at least 2–3 seconds of following distance under normal conditions. This allows enough time to react to any sudden stops or changes in traffic flow. It is important to increase the following distance in adverse weather conditions or when driving at higher speeds.
~200 feet.
If there is, it has not yet beed discovered.
