To be a part of God's universe, then, is to see the collisions in our lives not as travesties we should have been able to swerve around, but rather as the inevitabilities of belonging to a universe that requires collision in order to expand.
It is not known how many of the collisions resulted from motor vehicles passing bicycles.

From the moment an impact is recognized as a collision to the moment of airbag inflation, only 0.
The binary exponential backoff (BEB), a widely used backoff algorithm, adjusts the contention window size by indirectly estimating the traffic in the communication medium at individual nodes, in effect by counting consecutive collisions involving the same packet.
For example, more sophisticated path determination algorithms fed by information from vision systems will extend the distance at which potential collisions can be identified, thus effectively offering a margin of safety at higher speeds.
DriveCam does not analyze collision events for legal reasons; however, extensive video event review of a driver's prior non-collision poor driving behaviors allows DriveCam to better understand those behaviors that act as leading indicators of collisions.
