HOV abusers: Move over

Each weekday my commute is about 70 miles round-trip. During this 70 mile journey I routinely see stupid unskilled drivers. Along I-65, as with most interstates these days, are signs like these:

Of course, on the northbound lanes it reads 4PM-6PM MON-FRI. The text is in plain english (which could be the problem) though every day there are multiple single-occupancy vehicles travelling in this lane around 4:30PM going 10 miles under the speed limit. To top it off, Nashville's finest Metro Nashville PD is busy pulling everybody and their brother over for speeding but seemingly ignore the fact that the HOV is being abused. Oh, the humanity!
