This. Speed limit laws are bullshit and their selective enforcement is proof of it.

The dangerous drivers are the ones that are impeding the flow (i.e. going well below the speed limit when road/weather conditions don't necessitate it; cruising in a passing lane, etc) or driving unpredictably/erratically (cutting people off, weaving, etc).

Not necessarily the speeders, though there can certainly be some overlap, particularly in the latter group.

But speeders are the ones that get ticketed over while those asshats just crash into schoolbusses.
