> the current limits on most roads don't represent what speed ... people could safely drive at. If there's a sidewalk or any t-junctions, that's about 20mph tops. Anything faster, and you can't stop in time, plus in a collision, kinetic energy goes as the square of the speed. For local trips, with stoplights that slow you down anyway, driving slower adds only a few extra minutes to your journey time. Personally, I'm not seeing the need to be so hurried all the time. http://www.rospa.com/roadsafety/adviceandinformation/driving/speed/inappropriate-speed.aspx http://www.rospa.com/roadsafety/adviceandinformation/driving... http://blog.americansafetycouncil.com/why-speeding-is-dangerous/ http://blog.americansafetycouncil.com/why-speeding-is-danger...
