That is a thought provoking short video. Well worth watching.
No question that speed greater than appropriate for conditions and a driver's ability substantially increase the consequence of a collision and increase the likelihood of a collision. You can find a lot of common sense from the Center for Transportation Safety HERE.
As the Center notes: "While most drivers are assumed to be capable of making reasonable judgments about appropriate driving speeds, speed limits are necessary because of the significant risks drivers can impose on others. Other reasons include some drivers’ inability to correctly judge the capabilities of their vehicles (e.g., stopping or handling) and the tendency to underestimate or misjudge the effects of speed on crash probability and severity"
It is also the case that speed limits are not always set with those laudatory principles in mind. For example, the speed limit on Lincoln Drive in NW Philadelphia is 25 MPH. Average speed is probably closer to 40 MPH and when conditions permit I have seen it safely transited at more than 50 MPH. According to the Center, when Texas raised its speed limit from 55 MPH to 70 MPH the average speed increased only about 7 MPH on urban highways and just 4 MPH on rural highways. Clearly not many drove at the 55 MPH limit.
Happily our Club has DE, AX and Street Survival practical training to help improve the ability of drivers to correctly judge the capabilities of their vehicles (e.g., stopping or handling). And have fun while doing so!
