The proper time interval between two events on a world line is the change in proper time, which is independent of coordinates, and is a Lorentz scalar. [1] The interval is the quantity of interest, since proper time itself is fixed only up to an arbitrary additive constant, namely the setting of the clock at some event along the world line.
The three second rule is a time for the defensive driver to judge the minimum safe trailing distance to help avoid collisions under ideal driving conditions. The red car's driver picks a tree to judge a two-second safety buffer. The two-second rule is a rule of thumb by which a driver may maintain a safe trailing distance at any speed.
A different term, proper distance, provides an invariant measure whose value is the same for all observers. Proper distance is analogous to proper time. The difference is that the proper distance is defined between two spacelike-separated events (or along a spacelike path), while the proper time is defined between two timelike-separated events ...
If one divides a change in proper distance by the interval of cosmological time where the change was measured (or takes the derivative of proper distance with respect to cosmological time) and calls this a "velocity", then the resulting "velocities" of galaxies or quasars can be above the speed of light, c.
Tailgating is the action of a driver driving behind another vehicle while not leaving sufficient distance to stop without causing a collision if the vehicle in front stops suddenly. [1] The safe distance for following another vehicle varies depending on various factors including vehicle speed, weather, visibility and other road conditions. Some ...

A method of collecting tolls on highways using toll barriers at regularly spaced intervals on the toll road's mainline, usually charging a flat rate at each barrier. Beltway. See ring road. Bicycle, bike, or cycle A human-powered or motor-powered, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other.
