Re: "raise property taxes slightly"
"Here in Oregon, there's 3 towns I can think of off the top of my head that when you hit the "city limit" sign, you best be doing the posted speed limit. And if you're driving a semi-trailer rig, the fine is even higher."
Assuming you are being serious rather than trolling and setting aside for the moment that some places feel reducing speed limits is a better way to improve road safety rather than teaching idiots to keep off the road/highway and out of the traffic, there is normally a reason for the posted speed limit and you probably shouldn't be going faster.
I am a driver and I often complain about the speed limit on some roads (especially when the gits* in charge decided to change it purely as a revenue stream**), but I also understand that the limit is there for a reason and it is not up to me to ignore it just because I don't like it.
I have also seen the results of idiots driving faster than is safe for the conditions and would say that, without exception, the bigger the vehicle the worse the carnage - so why should being an idiot in a semi not be punished harder than someone being an idiot in a car?
*Git = 'Awkward or obtuse person', which describes some of the people responsible for deciding speed limits in the UK perfectly.
**There are several roads in the south-east of England that were, for many years, "national speed limit" roads and people rarely had accidents on them. Then, when the local authorities could keep (some or all of) the revenue generated, these same roads suddenly became accident black spots and the gits reduced the limits on a load of them but somehow managed to forget to put the new signs up where they could easily be seen (A24 Michelham Bends between Leatherhead and Dorking was the first and best example to spring to mind - there are many, many more!). Or they will slowly extend "temporary" reductions brought in for road maintenance work and "forget" to remove these when the work is completed.
