&gt; Majority of people drive at or slightly below the speed limit.<p>For my entire driving experience, from the North East of the US to Northern California, to specificially the portion of the road this car was driving on, this is false. People drive, very reliably, ~5mph over the speed limit. When you get to 35&#x2F;40+ mph speed limits, ~10 over isn&#x27;t uncommon, ~15 for people going uncommonly fast. I can&#x27;t recall the last time I drove under a speed limit (minus exceptional road&#x2F;traffic&#x2F;weather conditions) and I&#x27;m slower than most drivers I encounter.
